To me they just looked a bit alike:
--- op's example ---
a = MyInt(10)
# Here i need to overwrite the assignement operator
a = 12
--- traits' example ---
moe = Child()
# NOTIFICATION in action

Could the "traits" package be of help?

You should try copy/paste - it's both safer and less work !-)

Okay, very well, then I put a couple of extra 'self' identifiers in
there when I hand-copied the code over. That would be my mistake for
letting my fingers do the walking and forgetting my brain. Is there
anything else wrong with my code?

The recursion problem doesn't occur with you original code (for the good

Interesting, I have used this construct before in Python 2.4.3 and not
run into the recursion problem you talk about. Also, it has worked
fine for me. Perhaps you can post a link to your source so that I
could study it and unders
Wow, thanks a lot for your quick answers.
That assignement is no operator, but a statemant is a pity, but indeed I came
foward with overwritten methods for numeric types

No.
We were just discussing the reasons why Python will not and can not have
an assignment operator just a few days ago. Check the archives for more
details.

You can't overwrite assignment operator, but you can
overwrite methods of numeric objects:
