Idea about method parameters

[Markus Schaber]

Hi,

in my Code, I very often have constructs like

class A:
    def m(self, value):
        self.value = value
        # some other work to be done

This is annoying especially when having lots of parameters, which often 
happens in __init__ methods.

Now I'd love to have the possibility to shorten this by typing:

class A:
    def m(self, self.value):
        pass # or the other work to be done

This should do exactly the same as:

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

This could save some lots of typing, and even make some methods much 
more readable in my eyes. 

I would consider it a rather pythonic construct - straightforward and 
clear.

The syntax to specify self.value inside the def statement is currently 
invalid (at least using Python 1.5.2 and 2.0.1), and so I don't expect 
it would break any existing code.

Maybe it is also sensible to allow A.value to assign to class variables 
(maybe even superclasses make sense here).

What do you think about it? Is it worth the effort to think more about 
it, and go the heavy way towards a PEP?
