Passing Filehandles

• Similarly:

        open my $fh, ...;

• This now creates a new filehandle and stores it in $fh

• What is actually created?

        print "$fh\n";
        GLOB(0x80f7b0c)

• A glob reference

• It's a glob that's not part of the symbol table

  • There are no aliasing effects on assignment

• In Perl 6, open will simply return a filehandle object:

         my $fh = open $filepath : mode=>'rw'

• It will probably stringify as something like IO(0x436c1d)
