Hi Francis
I don't think it's safe to assume f_code is properly filled by the
time you might read it, depending a bit where you find the frame
object. Are you sure it's not full of garbage?
Besides, are you writing a profiler, or what exactly are you doing?

I would like to point out that we implemented rhettingers idea in PyPy
that makes all the dicts ordered by default and we don't have any
adverse performance effects (in fact, there is quite significant
memory saving coming from it). The measurments on CPython could be
different, but in
Not all your examples are good.
* float(x) calls __float__ (not __int__)
* re.group requires __eq__ (and __hash__)
* I'm unsure about OSError
* the % thing at the very least works on pypy

I presume the reason was that noone wants to maintain code for the
case where there are no buildbots available and there is no
development time available. You are free to put back in the files and
see if they work (they might not), but such things are usually removed
if they're a maintenance

very skeptical how well it works on less used platforms)

I think we should look into getting speed.python.org up and
running for both Python 2 and 3 branches:

What would it take to make that happen ?
