This is why I gave the following semantic definition:

class A:
    def m(self, value):
        self.value = value
        del value
        #the other work here

This is completely valid python semantics, at least since 1.5.2 (if I 
got it correctly), and it may even be implemented as a preprocessor 
like mechanism during testing / as a first step: 

Parse the parameter list from left to right, beginning with the second 
parameter. Whenever you get to a parameter that has a dot in it, and 
the part before the dot equals to the first (self per convention) 
parameter (or the class name or a superclass name), replace the 
parameter with the part of the right side of the dot (keeping an 
eventual default value declaration which begins with =). Then insert 
the assignment and the del statement after the def: statement (just 
after other generated assignments to keep the left-to-right order, but 
before any user specified code).
