*Learning Python* (pp. 99-105) points out that declaring globals from
within functions is possible, and shows how. I'm trying to think of
*why* one might want to declare or modify a global from within a

A friend who knows quite a bit more than I do about the subject said
"That's the first thing about python I've seen that really makes me go
"yecchhh.".  Global variables have to be declared outside the scope of
