I'm not too familiar with Ruby, but the important part here in Perl is
that it's not a "foo()" v.s. "foo" shortcut for a function invocation,
it's unambiguous whether that is a function and what its arguments are
until at that point in the program. Perl has dynamic grammar, you can't
parse it with a regular grammar without executing it.
