Sorry if my message offended anyone (noted that the "Toxic Forum" post came
not long after mine).
What I meant is that I cannot defend such an idea before extensively using
it. I just don't know how to do it this way.
Have a great day

Python-ideas
I like type() a lot, and the attributes dict it takes as argument works
with lambda.
My use case is just a python module for a framework provides a default
instance for some model, and I thought it would be cool to just change a
method without going through
I'm really bad at defending ideas,
Here is an example of how it could be done.

Why are you using

def o.bar(self): ...
You could get almost the same effect with
from functools import partial
def bar(self, other_args):
...
o.bar = partial(bar, o)
But IMO this is nowhere near being a common enough thing to
do to justify having special syntax for it.

I think C# calls methods that are added to a class "extension methods".
You can make a decorator that will do that for you:

Hi Jamesie
Thank you for your question. You asked why not

I've the same same query, but never had the courage to ask. So that
you for asking. And also giving me a chance to share my thoughts.
In Ruby, I believe, you can
