I agree with Alex that this is too lumped together; not everyone who
dislikes a specific new feature dislikes all new features. Not even most,
and not even close.

New library modules are indeed cool with most people.

That's of interest to almost nobody; PLabs wants it mostly to make it
*possible* to do more intense program analysis without the code driving us
insane (the current parser+codegen code is already pushed beyond its
> an exposed parser,
The audience for that is also small, unless it's an all-things-to-all-people
kind of parser.
> unified ints/longs,
People are definitely going to howl about finishing this one. People who
used to strip the trailing 'L' from str(long) via str(long)[:-1] found
themselves throwing away the last digit after str(long) stopped producing a
trailing 'L'. What did they do instead? Almost every workaround I've seen
amounted to doing repr(long)[:-1] instead. When repr(long) stops producing
a trailing 'L' too, they're going to feel thrice screwed. That one's a
special bitch, because it's neither the repr() nor the slice in isolation
that creates the problem, so it's hard to give a sharp warning. Code is
also going to break when, e.g., "1 << 100" stops producing 0, but at least
that one can be warned about in a focused way.
> and optimized variable access.
People do have a mild appreciation for speedups. Forget what you read about
this on c.l.py, though: the true market for speedups is smaller than you'd
guess for all the whining about this that goes on. Of course it doesn't
help that all the speedup work that's gone on since 1.5.2 (and yes, there
has been some, and some of it difficult) has been more than wiped out by the
expense of new features. So far, CVS 2.3 is significantly faster than
2.2.1, but we've got lots of time to blow that too <wink>.

Stick around <wink>.

It would enjoy a strong counter-reaction, but so far none of those are
deprecated. I'm delighted to see you didn't put "reduce" in that list
(almost always both more obscure and slower than the obvious loop).

You're not. Guido wants all of your kind to go away, though <wink>.
