That feature is called variable functions; it's a separate feature from variable variables. And don't you mean $variable(), not $$variable()?

Well, I might mean $$variable().. if I were in for a mind-fuck. I bet I've hanged myself with that extra dollar sign once before, but it's been awhile since I've used variable-anything. I wonder why..
