Normally, things at the module level can only be modified by other
lines at the module level, or by monkey-patching. The global
statement changes that.
>>> x=5 # Safe ... no other assignments on the far left ...
>>> class T:
x=4 # OK, so there is a class level variable
global x # which, alas, isn't what gets used
<__main__.T object at 0x0137A270>
Wait -- how did x get changed? *I* didn't change it, did I?
