Really drastic performance degradations would be on the radar as well -
slowing pprint() down by 10% is unlikely to bother anyone, but slowing
it down by 100% would be a bad thing (not that I think such a
degradation is likely, I'm just trying to give an impression of the
magnitude of change I'll be trying to measure).
Using the pretty module I referenced earlier, which basically uses
simplegeneric's lookup algorithm:
In [11]: %timeit x=pprint.pformat(sys.modules)
10 loops, best of 3: 27.5 ms per loop
In [12]: %timeit x=pretty.pretty(sys.modules)
10 loops, best of 3: 39.9 ms per loop
In [13]: len(sys.modules)
Out[13]: 517
The comparison is somewhat dodgy, though. pretty is not so much a refactoring of
pprint as a reimplementation, so the time differences may not be due to the
dispatch.
