-# scopes, or :short may be in effect or not effect in different scopes,
-# or various combinations thereof.  This was solved in this version
-# mostly by moving things to %^H.  But some things couldn't be moved
-# there.  One of them was the cache of runtime looked-up names, in part
-# because %^H is read-only at runtime.  I (khw) don't know why the cache
-# was run-time only in the previous versions: perhaps oversight; perhaps
-# that compile time looking doesn't happen in a loop so didn't think it
-# was worthwhile; perhaps not wanting to make the cache too large.  But
-# I decided to make it compile time as well; this could easily be
-# changed.
-# Anyway, this hash is not scoped, and is added to at runtime.  It
-# doesn't have scoping problems because the data in it is restricted to
-# official names, which are always invariant, and we only set it and
-# look at it at during :full lookups, so is unaffected by any other
-# scoped options.  I put this in to maintain parity with the older
-# version.  If desired, a %short_names cache could also be made, as well
-# as one for each script, say in %script_names_cache, with each key
-# being a hash for a script named in a 'use charnames' statement.  I
-# decided not to do that for now, just because it's added complication,
-# and because I'm just trying to maintain parity, not extend it.

+
+By specifying C<:loose>, Unicode's L<loose character name
+matching|http://www.unicode.org/reports/tr44#Matching_Rules> rules are
+selected instead of the strict exact match used otherwise.
+That means that I<CHARNAME> doesn't have to be so precisely specified.
+Upper/lower case doesn't matter (except with scripts as mentioned above), nor
+do any underscores, and the only hyphens that matter are those at the
+beginning or end of a word in the name (with one exception:  the hyphen in
+U+1180 C<HANGUL JUNGSEONG O-E> does matter).
+Also, blanks not adjacent to hyphens don't matter.
+The official Unicode names are quite variable as to where they use hyphens
+versus spaces to separate word-like units, and this option allows you to not
+have to care as much.
+The reason non-medial hyphens matter is because of cases like
+U+0F60 C<TIBETAN LETTER -A> versus U+0F68 C<TIBETAN LETTER A>.
+The hyphen here is significant, as is the space before it, and so both must be
+included.
+
+C<:loose> slows down look-ups by a factor of 2 to 3 versus
+C<:full>, but the trade-off may be worth it to you.  Each individual look-up
+takes very little time, and the results are cached, so the speed difference
+would become a factor only in programs that do look-ups of many different
+spellings, and probably only when those look-ups are through C<vianame()> and
+C<string_vianame()>, since C<\N{...}> look-ups are done at compile time.

+As mentioned above under L</ALIASES>, Unicode 6.1 defines extra names
+(synonyms or aliases) for some code points, most of which were already
+available as Perl extensions.  All these are accepted by C<\N{...}> and the
+other functions in this module, but C<viacode> has to choose which one
+name to return for a given input code point, so it returns the "best" name.
+To understand how this works, it is helpful to know more about the Unicode
+name properties.  All code points actually have only a single name, which
+(starting in Unicode 2.0) can never change once a character has been assigned
+to the code point.  But mistakes have been made in assigning names, for
+example sometimes a clerical error was made during the publishing of the
+Standard which caused words to be misspelled, and there was no way to correct
+those.  The Name_Alias property was eventually created to handle these
+situations.  If a name was wrong, a corrected synonym would be published for
+it, using Name_Alias.  C<viacode> will return that corrected synonym as the
+"best" name for a code point.  (It is even possible, though it hasn't happened
+yet, that the correction itself will need to be corrected, and so another
+Name_Alias can be created for that code point; C<viacode> will return the
+most recent correction.)
+
+The Unicode name for each of the control characters (such as LINE FEED) is the
+empty string.  However almost all had names assigned by other standards, such
+as the ASCII Standard, or were in common use.  C<viacode> returns these names
+as the "best" ones available.  Unicode 6.1 has created Name_Aliases for each
+of them, including alternate names, like NEW LINE.  C<viacode> uses the
+original name, "LINE FEED" in preference to the alternate.  Similarly the
+name returned for U+FEFF is "ZERO WIDTH NO-BREAK SPACE", not "BYTE ORDER
+MARK".
+
+Until Unicode 6.1, the 4 control characters U+0080, U+0081, U+0084, and U+0099
+did not have names nor aliases.
+To preserve backwards compatibility, any alias you define for these code
+points will be returned by this function, in preference to the official name.
+
+Some code points also have abbreviated names, such as "LF" or "NL".
+C<viacode> never returns these.
+
+Because a name correction may be added in future Unicode releases, the name
+that C<viacode> returns may change as a result.  This is a rare event, but it
+does happen.

-vianame returns a chr if the input name is of the form C<U+...>, and an ord
-otherwise.  It is proposed to change this to always return an ord.  Send email
-to C<perl5-porters@perl.org> to comment on this proposal.  If S<C<use
-bytes>> is in effect when a chr is returned, and if that chr won't fit
-into a byte, C<undef> is returned instead.

+vianame() normally returns an ordinal code point, but when the input name is of
+the form C<U+...>, it returns a chr instead.  In this case, if C<use bytes> is
+in effect and the character won't fit into a byte, it returns C<undef> and
+raises a warning.

 
 Names must be ASCII characters only, which means that you are out of luck if
 you want to create aliases in a language where some or all the characters of
 the desired aliases are non-ASCII.
