Summary: globaling a variable twice issues warn

Initial Comment:
The following code generates a warning:

def foo():
    global dammit
    dammit = 5
    global dammit

test.py:1: SyntaxWarning: name 'dammit' is assigned to
before global declaration  def foo():

One would argue that this should still issue a warning,
but the warning it raises is a bit confusing
(especially when the two global statements are 100
lines apart).

I kinda agree that it's probably not worthwile to change the
compiler to handle this as it's probably a rare thing to
have happen.  The main reason I had the second global
statement is that I del'd the global'd variable in between
and I wasn't sure if the global would stick.  I guess I know
tha I don't have to worry about it now. :)

Thanks

When you see the warning, you should remove the global 
declaration that comes after the assignment.  It doesn't 
seem worthwhile to add extra complexity to the compiler to 
handle this.

Maybe the function is too long if the two global decls are 
100 lines apart <0.9 wink>.
