Of course, that's what I'd do under normal internet conditions :) 
Right now, however, my own personal box (and thus, my development box)
isn't able to connect to the internet, and is a bit of a drive away
from here, where I do connect to the internet from.

I'm having a modem mailed to me, but until it arrives, testing little
code fragments like that does actually take more time than posting the
question.  Sorry, though; I completely understand your frustration
(and would probably feel the same way myself in those circumstances).
