er, why not just drop the prototypes since they will
likely cause you more problems than they're worth,
use the standard passing and deal with is $_[0]?

	my $something = shift;

	ref $something or croak "Bogus something: arg not a referent";

	# add a separate test for ref $something ~= /FOOBAR/ if you
	# really care. at that point anyone following you has some
	# pretty specific internal docs on exactly what's going on
	# in the tests and error messages.


	$something->else;

or

	else $something;

or

	else shift;

or

	or $_[0]->else;
