-(F) You're on a system such as MS-DOS that gets confused if you try
-reading from a deleted (but still opened) file. You have to say
-C<-i.bak>, or some such.

=item Can't do inplace edit: %s would not be unique
(S inplace) Your filesystem does not support filenames longer than 14

+(F) You used something like C<\b{}>, C<\B{}>, C<\o{}>, C<\p>, C<\P>, or
+C<\x> without specifying anything for it to operate on.
+
+Unfortunately, for backwards compatibility reasons, an empty C<\x> is
+legal outside S<C<use re 'strict'>> and expands to a NUL character.

+=item Empty (?) without any modifiers in regex; marked by <-- HERE in m/%s/
+
+(W regexp) (only under C<S<use re 'strict'>>)
+C<(?)> does nothing, so perhaps this is a typo.
=item ${^ENCODING} is no longer supported
(F) Named Unicode character escapes (C<\N{...}>) may return a
multi-character sequence. Even though a character class is
supposed to match just one character of input, perl will match the
-whole thing correctly, except when the class is inverted (C<[^...]>),
-or the escape is the beginning or final end point of a range. The

+=item When the class is inverted (C<[^...]>)
+
+The mathematically logical behavior for what matches when inverting
is very different from what people expect, so we have decided to
-forbid it. Similarly unclear is what should be generated when the
+forbid it.

+=item The escape is the beginning or final end point of a range
+
+Similarly unclear is what should be generated when the
C<\N{...}> is used as one of the end points of the range, such as in
[\x{41}-\N{ARABIC SEQUENCE YEH WITH HAMZA ABOVE WITH AE}]
What is meant here is unclear, as the C<\N{...}> escape is a sequence
of code points, so this is made an error.
+=item In a regex set
+
+The syntax S<C<(?[ ])>> in a regular expression yields a list of
+single code points, none can be a sequence.

=item No %s allowed while running setuid
(F) Certain operations are deemed to be too insecure for a setuid or
of Perl. Check the #! line, or manually feed your script into Perl
yourself.
-=item (?[...]) not valid in locale in regex; marked by S<<-- HERE> in m/%s/
-
-(F) C<(?[...])> cannot be used within the scope of a C<S<use locale>> or with
-an C</l> regular expression modifier, as that would require deferring
-to run-time the calculation of what it should evaluate to, and it is
-regex compile-time only.

=item no UTC offset information; assuming local time is UTC
(S) A warning peculiar to VMS. Perl was unable to find the local
a number. This happens, for example with C<\o{}>, with no number between
the braces.
+=item Numeric format result too large
+
+(F) The length of the result of a numeric format supplied to sprintf()
+or printf() would have been too large for the underlying C function to
+report. This limit is typically 2GB.
+
=item Octal number > 037777777777 non-portable
(W portable) The octal number you specified is larger than 2**32-1
operators treat their operands as strings of bytes, and values beyond
0xFF are nonsensical in this context.
