Sweet so, I think

$a = 'my_func';

does it for me. I'd love to understand the following code, but I'll have to
read it a couple more times. Haven't quite gotten into classy stuff like
this yet. Looks like actionscript to me with this execute function.

Thanks so much. I didn't expect to get this good an answer.
