I also think that this could have several benefits to it, as you could 
probably quite easily implement separate behaviors for constructors and 
conventional methods.

This would probably be the most useful pattern for constructors:

class MyClass:
     def __init__(self, arg = None):
         if arg is None:
             arg = list()
         self.arg = arg

while you probably would want to do this for other methods:

class MyClass:
     def method(self, arg = None):
         if arg is None:
             arg = self.arg

How does that sound to you? Is it reasonable? It's certainly true for my 
style of coding anyway.

I elaborated on the rationale for doing things this way in the use case 
docs for AssignToAttributeOfSelf (if I'm allowed to repeat myself... :-)

'''It's often a good idea to use the same names in args, variables and 
data members. This keeps the terminology consistent. This way 
customer_id should always contain a customer id, and any other variants 
are misspellings that probably will lead to bugs.'''

What do you think?
