[Python-Dev] Using and binding relative names (was Re: PEP for Better Control of Nested Lexical Scopes)

[Massimiliano Leoni]

Why would you change the Python scoping rules, instead of using the 
function attributes, available from release 2.1 (PEP 232) ?
For example, you may write:

def incgen(start, inc):
   def incrementer():
     incrementer.a += incrementer.b
     return incrementer.a
   incrementer.a = start - inc
   incrementer.b = inc
   return incrementer

f = incgen(100, 2)
g = incgen(200, 3)
for i in range(5):
     print f(), g()

The result is:

100 200
102 203
104 206
106 209
108 212
