No need to feel bad about it :) Getting your head around "this is a
function, that's where the function's being called" is not easy, and

Your question was very well put. You provided a short, compact example
that showcased the problem you were experiencing. That made it easy to
answer your question. Keep on asking questions like that, please -
you're helping yourself and making the mailing list a great place too
:)
