A little disappointed so far

Syntactically, it would be definitately 'unPythoninc' for a operator
to have such a side-effect.  But if wanted badly enough....

def pi(gvname): # post increment global variable
    g = globals()
    t = g[gvname]
    g[gvname] =  t+1
    return t

x = 1
y=pi('x')
print x, y
# prints 2 1

but this only works for code at module level.  (For generality, a
*lot* more would be needed to get the calling frame, decide if modular
or functional, and if the latter, fiddle with the function's local
vars -- though I believe it might be possible based on what people
have posted at various times ;-)

Good.  It would never make it into Python.
