Good points. Well, this is pretty academic at this point - I don't think
anyone would seriously choose to obsolete __ne__, regardless of whether it
is absolutely necessary or not.

Ugh, right, for NaN you can have (x < y) != (x >= y) - both would be false
if one of x and y is a NaN.
But __ne__ is still useless ;-)

I don't see a case in IEEE where (x == y) != !(x != y).
There _is_ a case where (x != x) is true (when x is NaN), but for such an
x, (x == x) will be false.
I am hard pressed to think of a case where __ne__ is actually useful.
That said, while it is true you only need one of (__eq__, __ne__), you
The first line says "The major reason is history." :-) But it also gives an
explanation: providing functionality for types that, at the time, didn't
have methods.

That doesn't explain why `del` isn't a method though. Intuitively,
`my_dict.delete(some_key)` makes sense as a method. Of course, you could
also make the same case for `len` being a method... and personally I think
it would have been cleaner that way in both cases. But it is a minor issue,

Yes, it sort-of makes sense... I'll basically re-post my question there.
Thanks for the link!

TL;DR: We need improved documentation of the way meta-classes behave for
generic classes, and possibly reconsider the way "__setattr__" and
"__getattribute__" behave for such classes.
I am using meta-programming pretty heavily in one of my projects.
It took me a while to figure out the dance betwe
You _can_ just extend a JSON file without loading it, but it will not be
"fun".
Say the JSON file contains a top-level array. The final significant
character in it would be a ']'. So, you can read just a reasonably-sized
block from the end of the file, find the location of the final ']',
