Thanks so much Ben for documenting all these examples. I've been frustrated
by the inconsistencies, but hasn't realized all of those you note.
It would be a breaking change, but I'd really vastly prefer if almost all
of those OverflowErrors and others were simply infinities. That's much
closer to

You're quite right, I have proposed it to have an opinion by experts.
Indeed I have no knowledge about how a parser works. This is why I

I also considered this issue simple and non-controversial. But the
discussion turned in an unexpected direc
I just had an idea: we have mp->ma_used and keys->dk_nentries.
holes = mp->ma_keys->dk_nentries - mp->ma_used
is the number of holes in the dict.
So, if holes == 0, you have O(1). But, if the dict has holes, you
can't have O(1), but you can speedup the check of the entry by
counting the NULLs in
Well, I didn't read the entire discussion... but I wrote in
unsuspicious times a stupid little module, msutils, with two stupid
little functions, jsonLoad and jsonDump:

In the meanwhile I tried to apply some tricks to speedup the dict
creation without success.
This is my effort:

As you can see, I simply "cloned" some functions that create dict, and
removed some checks that

I think not; unless there are API details to be hashed out or
counterarguments to be rebuffed, I think this is fairly simple and
non-controversial.

There seems to be a fair bit of support for this idea.
Will it need a PEP ?

To me it seems like a useful shortcut that means:
>>> x == True and type(x) == bool
But, as you say, it is best to just let the Python interpreter treat it as
a boolean (i.e. within an `if`, it is converted automatically)
Now, I am thinking it would actually be *bad* to have the CPython
