in thread Where to find info on low level perl internals names?

GV is a "glob", short for "typeglob", as in "a bunch of types". They are used as symbol table entries, although they can exist outside the symbol table, so they aren't necessarily global. open my $fh, ... populates $fh with a reference to a "non-global" glob.

    And what do you think the 'glob' in 'typeglob' stands for?

      I figured "glob" actually meant "glob". It really doesn't matter what it stands for, since we're talking about what GV stands for.

        =head1 GV Functions

        A GV is a structure which corresponds to to a Perl typeglob, ie *foo. It is a structure that holds a pointer to a scalar, an array, a hash etc, corresponding to $foo, @foo, %foo.

        GVs are usually found as values in stashes (symbol table hashes) where Perl stores its global variables. =cut

        Game, set, and match!
