Use scalar filehandles? You're probably thinking of 5.6.0, which was
the first that would let you autovivify filehandles. As far as I
know, through the 5.x series you could always do:
my $fh = do {local *fh};
open($fh, "< $somefile") or die "Can't read '$somefile': $!";
If you didn't remember the do local trick, you could always use Symbol
and then call gensym to get your typeglob.
As for passing old-style filehandles, both of the following syntaxes
are likely to work:
call_function(*FILEHANDLE);
call_function(\*FILEHANDLE);
