This is the paradigmatic reason why I don't want this in the stdlib.

They don't. They matter for durations, because humans regularly do
things like schedule a meeting for "one week from today" and then have

In CPython we have reference counting. My question is can we optimize current
RC using strategies like Deferred RC and Coalescing? If no then where would I
face problem if I try to implement these sorts of strategies?
These strategies all depend on the concept that we don't need the exact value

Python's cyclic GC collector uses exact reference count.

I have a proposal for an addition to the dataclasses module that I think would

easier to use private and name mangled variables. One of the benefits of the
dataclass
decorator is that it helps lessen the amount of code when you just need a simple
constructor. A common pattern in python th

That is one of the
I think it is worth directly discussing the availability of slices in PEP
472-style keyword indices, since we seem to have mostly converged on a
dunder method signature. This is an issue that has been alluded to
regarding keyword-based (labelled) indices but not directly addressed. The

But thus brings up a broader question:
Why not allow slice syntax as an expression everywhere? Everywhere I’ve
