[Python-ideas] Default arguments in Python - the return

[Scott David Daniels]

Any argument for changing to a more "dynamic" default scheme had better
have a definition of the behavior of the following code, and produce a
good rationale for that behavior:

     x = 5
     def function_producer(y):
         def inner(arg=x+y):
             return arg + 2
         return inner

     x = 6
     f1 = function_producer(x)
     x = 4.1
     y = 7
     f2 = function_producer(3)
     print x, y, f1(), f2()
     del y
     x = 45
     print x, f1(), f2()
     del x
     print f1(), f2()
