-=item charnames alias definitions may not contain a sequence of multiple spaces
-
-(F) You defined a character name which had multiple space characters
-in a row. Change them to single spaces. Usually these names are
-defined in the C<:alias> import argument to C<use charnames>, but they
-could be defined by a translator installed into C<$^H{charnames}>. See
-L<charnames/CUSTOM ALIASES>.
-
-=item charnames alias definitions may not contain trailing white-space
-
-(F) You defined a character name which ended in a space
-character. Remove the trailing space(s). Usually these names are
-defined in the C<:alias> import argument to C<use charnames>, but they
-could be defined by a translator installed into C<$^H{charnames}>.
-See L<charnames/CUSTOM ALIASES>.

=item assertion botched: %s
(X) The malloc package that comes with Perl had an internal failure.
must either both be scalars or both be lists. Otherwise Perl won't
know which context to supply to the right side.
+=item <> at require-statement should be quotes
+
+(F) You wrote C<< require <file> >> when you should have written
+C<require 'file'>.
+
=item Attempt to access disallowed key '%s' in a restricted hash
(F) The failing code has attempted to get or set a key which is not in
iterate over %ENV, it encountered a logical name or symbol definition
which was too long, so it was truncated to the string shown.
-=item \C is deprecated in regex; marked by <-- HERE in m/%s/
-
-(D deprecated, regexp) The \C character class is deprecated, and will
-become a compile-time error in a future release of perl (tentatively
-v5.24). This construct allows you to match a single byte of what makes up
-a multi-byte single UTF8 character, and breaks encapsulation. It is
-currently also very buggy. If you really need to process the individual
-bytes, you probably want to convert your string to one where each
-underlying byte is stored as a character, with utf8::encode().
-
=item Callback called exit
(F) A subroutine invoked from an external package via call_sv()
unpack("s", "\x{f3}b")

=item "\c%c" is more clearly written simply as "%s"
(W syntax) The C<\cI<X>> construct is intended to be a way to specify
function, i.e. C<\p{IsFoo}> or C<\p{InFoo}>.
See L<perlunicode/User-Defined Character Properties> and L<perlsec>.
-=item In '(?...)', the '(' and '?' must be adjacent in regex;
-marked by S<<-- HERE> in m/%s/
-
-(F) The two-character sequence C<"(?"> in this context in a regular
-expression pattern should be an indivisible token, with nothing
-intervening between the C<"("> and the C<"?">, but you separated them
-with whitespace.
-
=item Integer overflow in format string for %s
(F) The indexes and widths specified in the format string of C<printf()>
operators arguments found inside the parentheses. See
L<perlop/Terms and List Operators (Leftward)>.

=item Invalid %s attribute: %s
(F) The indicated attribute for a subroutine or variable was not recognized
other cases where we can statically determine that arguments to
functions are missing, e.g. for the L<perlfunc/pack> function.
-=item Redundant argument in %s
-
-(W redundant) You called a function with more arguments than other
-arguments you supplied indicated would be needed. Currently only
-emitted when a printf-type format required fewer arguments than were
-supplied, but might be used in the future for e.g. L<perlfunc/pack>.
-
=item Missing argument to -%c
(F) The argument to the indicated command line switch must follow
(S syntax) This is an educated guess made in conjunction with the message
"%s found where operator expected". Often the missing operator is a comma.
+=item Missing or undefined argument to require
+
+(F) You tried to call require with no argument or with an undefined
+value as an argument. Require expects either a package name or a
+file-specification as an argument. See L<perlfunc/require>.
+
=item Missing right brace on \%c{} in regex; marked by S<<-- HERE> in m/%s/
(F) Missing right brace in C<\x{...}>, C<\p{...}>, C<\P{...}>, or C<\N{...}>.
F<SYS$TIMEZONE_DIFFERENTIAL> to translate to the number of seconds which
need to be added to UTC to get local time.

-(F) You tried to call require with no argument or with an undefined
-value as an argument. Require expects either a package name or a
-file-specification as an argument. See L<perlfunc/require>.
-
=item NULL OP IN RUN
(S debugging) Some internal routine called run() with a null opcode
folding rules are not accurate. This may lead to incorrect results.
Please report this as a bug using the L<perlbug> utility.

+experimental. If you want to take the risk of using this layer,

+
=item Perl_my_%s() not available
(F) Your platform has very uncommon byte-order and integer size,
Both numeric and string values are accepted, but note that string values are
case sensitive. The default for this setting is "RANDOM" or 1.

crude check that bails out after 100 levels of C<@ISA> depth.

=item refcnt: fd %d%s
interpreted as the != (numeric not equal) and ~ (1's complement)
operators: probably not what you intended.

-
-(F) You wrote C<< require <file> >> when you should have written
-C<require 'file'>.
-
=item /%s/ should probably be written as "%s"
(W syntax) You have used a pattern where Perl expected to find a string,
