Some of these messages are generic. Spots that vary are denoted with a %s,
just as in a printf format. Note that some messages start with a %s!

by Perl. This combination appears in an interpolated variable or a
C<'>-delimited regular expression.
+=item /%s/ should probably be written as "%s"
+
+(W) You have used a pattern where Perl expected to find a string,
+like in the first argument to C<join>. Perl will treat the true
+or false result of matching the pattern against $_ as the string,
+which is probably not what you had in mind.
+
=item %s (...) interpreted as function
(W) You've run afoul of the rule that says that any list operator followed
from a deleted (but still opened) file. You have to say C<-i.bak>, or some
such.
-=item Can't do inplace edit: %s E<gt> 14 characters
+=item Can't do inplace edit: %s would not be unique
-(S) There isn't enough room in the filename to make a backup name for the file.
+(S) Your filesystem does not support filenames longer than 14
+characters and Perl was unable to create a unique filename during
+inplace editing with the B<-i> switch. The file was ignored.
=item Can't do inplace edit: %s is not a regular file
(F) You aren't allowed to assign to the item indicated, or otherwise try to
change it, such as with an auto-increment.
+=item Can't modify non-lvalue subroutine call
+
+(F) Subroutines used in lvalue context should be marked as such, see
+L<perlsub/"Lvalue subroutines">.
+
=item Can't modify nonexistent substring
(P) The internal routine that does assignment to a substr() was handed
was currently active, which is not allowed. If you really want to do
this, you should write C<sort { &func } @x> instead of C<sort func @x>.
+=item Can't remove %s: %s, skipping file
+
+(S) You requested an inplace edit without creating a backup file. Perl
+was unable to remove the original file to replace it with the modified
+file. The file was left unmodified.
+
=item Can't rename %s to %s: %s, skipping file
-(S) The rename done by the B<-i> switch failed for some reason, probably because
-you don't have write permission to the directory.
+(S) The rename done by the B<-i> switch failed for some reason,
+probably because you don't have write permission to the directory.
=item Can't reopen input pipe (name: %s) in binary mode
(F) The return statement was executed in mainline code, that is, where
there was no subroutine call to return out of. See L<perlsub>.
+=item Can't return %s from lvalue subroutine
+
+(F) Perl detected an attempt to return illegal lvalues (such
+as temporary or readonly values) from a subroutine used as an lvalue.
+This is not allowed.
+
=item Can't stat script "%s"
(P) For some reason you can't fstat() the script even though you have
(W) You tried to do a listen on a closed socket. Did you forget to check
the return value of your socket() call? See L<perlfunc/listen>.
+=item Lvalue subs returning %s not implemented yet
+
+(F) Due to limitations in the current implementation, array and hash
+values cannot be returned in subroutines used in lvalue context.
+See L<perlsub/"Lvalue subroutines">.
+
=item Method for operation %s not found in package %s during blessing
(F) An attempt was made to specify an entry in an overloading table that
(F) A sort comparison subroutine may not return a list value with more
or less than one element. See L<perlfunc/sort>.
-=item split /^/ better written as split /^/m
-
-(W) Implicit translation of /^/ to mean /^/m in split is deprecated.
-
=item Split loop
(P) The split was looping infinitely. (Obviously, a split shouldn't iterate
