checksumming process loses information, and you can't go the other
way. See L<perlfunc/unpack>.
+=item /%s/: Unrecognized escape \\%c passed through
+
+(W) You used a backslash-character combination which is not recognized
+by Perl. This combination appears in an interpolated variable or a
+C<'>-delimited regular expression.
+
=item %s (...) interpreted as function
(W) You've run afoul of the rule that says that any list operator followed
(F) You called C<perl -x/foo/bar>, but C</foo/bar> is not a directory
that you can chdir to, possibly because it doesn't exist.
+=item Can't check filesystem of script "%s"
+
+(P) For some reason you can't check the filesystem of the script for nosuid.
+
=item Can't coerce %s to integer in %s
(F) Certain types of SVs, in particular real symbol table entries
Either qualify the sort variable with the package name, or rename the
lexical variable.
+=item Bad evalled substitution pattern
+
+(F) You've used the /e switch to evaluate the replacement for a
+substitution, but perl found a syntax error in the code to evaluate,
+most likely an unexpected right brace '}'.
+
=item Can't use %s for loop variable
(F) Only a simple scalar variable may be used as a loop variable on a foreach.
(S) A warning peculiar to VMS. Perl keeps track of the number
of times you've called C<fork> and C<exec>, to determine
whether the current call to C<exec> should affect the current
-script or a subprocess (see L<perlvms/exec>). Somehow, this count
+script or a subprocess (see L<perlvms/"exec LIST">). Somehow, this count
has become scrambled, so Perl is making a guess and treating
this C<exec> as a request to terminate the Perl script
and execute the specified command.
(F) While certain functions allow you to specify a filehandle or an
"indirect object" before the argument list, this ain't one of them.
+=item Missing command in piped open
+
+(W) You used the C<open(FH, "| command")> or C<open(FH, "command |")>
+construction, but the command was missing or blank.
+
=item Missing operator before %s?
(S) This is an educated guess made in conjunction with the message "%s
in your Perl script (or eval). Perhaps you tried to run a compressed
script, a binary program, or a directory as a Perl program.
+=item Unrecognized escape \\%c passed through
+
+(W) You used a backslash-character combination which is not recognized
+by Perl.
+
=item Unrecognized signal name "%s"
(F) You specified a signal name to the kill() function that was not recognized.
