At some point of Perl history returning globs from subroutines was
just asking for trouble.  Almost nothing worked.

I think I have some mindblocks left from this time.  I still cannot
make myself return *GLOB if returning \*GLOB works (as it should).  It
does no help that \*GLOB is a scalar, not some obscure aggregate of
heavy magical things...
