Thanks for taking the time to explain that for me, David.
Yeah, reading back over that I see it sounded kind of weird. I had made
an assumption (I know, I know) that the function declared after the
variable foo was running in the same or subordinate scope as the
variable itself was declared --- whether global or not didn't seem to
matter, but was convenient to write.
So that is definitely where I tripped, because I'm used to dumb
procedural languages (think VBScript and PL/SQL) that work more in that
fashion. I've hacked Python enjoyably, but never fully delved into the
deeper aspects of the language.
Looks like I still have a lot to learn to fully understand Ruby. Luckily
I came to the right place! :)
