New submission from Andreas Kloeckner:
The attached program uncovers a two-fold performance regression in
Python 2.5 with respect to Python 2.4. Below, the "element-wise" case
goes from 2.5 seconds in 2.4 to about 4 in 2.5. Since that's a pretty
serious increase, I thought I

This here basically says it all:

Other than point at how boost.math does things, I don't have the time to work
on this right now, s

The fix breaks my package PyCUDA, which relies on handing struct something that
can be cast to long. (i.e. not a float, but something representing a memory
address on a GPU)
Am I out of luck?

AFAICS, __index__ would be fine.
To make sure I understand your proposed solution correctly: You'd go through
the argument list beforehand and cast everything that's not a number type or
str to int by means of

Thanks for the clarification of 'beforehand'--I had understood from your
description that this would be some sort of preprocessing step.
I agree that the TypeError is a bit much, though I'm biased of course. If you'd

The "name" argument to PyErr_NewException() should be changed from "char
*" to "const char *". Since the rest of pyerrors.h is const-correct,
this seems like an omission.

For tests and doctests, it is often desirable to show or verify that a certain
warning occurs. Unfortunately, if the warning has been hit previously, it will
not be issued again. It would be great if there were a documented, unified way
to reset this

Vladislav: The behavior you find funny is actually correct. "pass" is a
statement and as such not allowed in a lambda. (only expressions are)

Steps to reprdocue:
1) Debug a program with a syntax error in pdb.
2) Get the SyntaxError traceback.
3) Hit "q" to quit.
4) Another SyntaxError traceback, and you're back at the Pdb prompt.

traceback.format_exception() used to work properly with the 'arg' value passed
