No. Just let it evolve naturally.
The next step is for a builtin C version. That will likely happen as
soon as one of us has the time and inclination to write it.
If that works out well, then writing decimal literals like 123d may be
plausible.
And, if that works out w
I've been looking at the API for sets.Set and built-in set objects in
Python 2.4.1 and I think I have found some minor inconsistencies.
Background: we have an object that is very similar to "sets" and we
originally modeled the API after sets.Set since we started with Python
2.3. Now I'm trying to

No. It was intentional to drop the duplicate method with the
hard-to-use name. There was some thought given to deprecating
sets.union_upda

This comment reminds me another small inconsistency/annoyance.

I think not.
Use copy.copy() for generic copying -- it works across a wide range of
objec
With 343 accepted, we can now add __enter__() and __exit__() methods to
objects.
What term should describe those objects in the documentation?
For instance, if the new magic methods are added to decimal.Context(),
do we then describe Context objects as "withable" ;-)
The PEP itself doesn't pro

Unless you happen to prefer the other current idiom:

list.clear() does not solve the root problem. The question is
symptomatic of not understanding slicing. Avoidance of tha

Hmm, don't know.
I talked about an object 'that conformed to the with protocol' at
EuroPython,
"Resource managed"?

One benefit I see for the path module is that it makes it easier to

Hi,
I'm sorry, I don't seem to have done a very good job at explaining
the situation. I'll try again:
'getch()' is a low-level function provided on Windows to capture a
single character of input from a user, /without echoing it to the
screen/. As far as I can tell there's no other way of doi
