I certainly understand saying "this change isn't important enough to justify a
change."
But it sounds as though you are saying the benefit is irrelevant; it is just
inherently too expensive to ask programs that are already dealing with
internals and trying to optimize performance to make a

Hi Serhiy,
Can I suggest using a short hash of the id as a prefix to the id?
would become something like:
This approach uses no extra memory in the object and makes similar
objects more visually distinct.
It fails to make the repr shorter, and the hashed ids are not globally
unique.
Without arguing for or against allowing a capture variable, IMO rather
than syntax like
match into :
it would be far better (and not require a new keyword) to write this as
with as match :

I agree they are "noise" mostly and difficult to distinguish when you
need to.
What if use serial numbers to differentiate instances?

How about putting it in parentheses, to point more clearly that it can

It will just make the repr 2 characters longer and will not solve other

While it would be nice to have simpler identifiers for objects, it would
be hard to make it work for multiprocessing, as objects in different

might also have different serial numbers

Yes, I understood that you were only talking about reprs, and

I like this idea. It is similar to how Jython and IronPython object IDs
work:
# Jython
>>> id(None)
2
>>>
15 matches
