Jeffrey Yasskin	57bd60b465	Working on issue #1762: Brought ... ./python.exe -m timeit -s 'from fractions import Fraction; f = Fraction(3, 2)' 'isinstance(3, Fraction); isinstance(f, Fraction)' from 12.3 usec/loop to 3.44 usec/loop and ./python.exe -m timeit -s 'from fractions import Fraction' 'Fraction(3, 2)' from 48.8 usec to 23.6 usec by avoiding genexps and sets in __instancecheck__ and inlining the common case from __subclasscheck__.	2008-02-13 17:58:04 +00:00

Guido van Rossum	64c06e327d	Backport of _abccoll.py by Benjamin Arangueren, issue 1383. ... With some changes of my own thrown in (e.g. backport of r58107).	2007-11-22 00:55:51 +00:00
Guido van Rossum	b55911378f	Patch # 1026 by Benjamin Aranguren (with Alex Martelli): ... Backport abc.py and isinstance/issubclass overloading to 2.6. I had to backport test_typechecks.py myself, and make one small change to abc.py to avoid duplicate work when x.__class__ and type(x) are the same.	2007-09-10 22:36:02 +00:00
