This seems to suggest that inside the function, you have to declare
SOMEVAR as a global variable:

Not sure if also declaring it as global near the top of you're program
makes a difference, but then I don't use Python very much. (Nor do I
often use global variables, so I'm not even sure what would be the
correct way to do this in Perl.)

Thanks Martijn. Just been discussing this on IRC with Mike. It would seem that I do have to declare each global that I want to use inside each function. Seems daft to me, but I can understand its value... and more importantly, I now know.

I would use Perl but for 2 thing (which are related):

1) Way too many {}; for my liking

2) I don't like Perl. :D
