Looks like I will have to read the Language Reference anyway. :-(

Clear now, but I have to say for someone who's been doing
some C programming in the past it is pretty confusing, because 
I'm used to think of any variable as basically a place in memory
with a pointer to it, so anything without #define or const was
considered "mutable" (gawd I still hate pointers).

C-style thinking considered harmful when programming in Python. :o)
