I hate to bring this up two months later, but that probably should have been CLONESKIP. perlsub says: Subroutines whose names are in all upper case are reserved to the Perl core, as are modules whose names are in all lower case. A subroutine in all capitals is a loosely-held convention meaning it will be called indirectly by the run-time system itself, usually due to a triggered event. Subroutines that do special, pre-defined things include C<AUTOLOAD>, C<CLONE>, C<DESTROY> plus all functions mentioned in L<perltie> and L<PerlIO::via>. which implies to me that such routines should match /^[A-Z]+\z/. Is it too late to change? Looks like this change didn't get mentioned in perl587delta.pod anyway.
