I certainly hope so! Here's a very simple (and simplistic) benchmark: # start benchmark from fractions import Fraction from cProfile import run def test1(): return sum(Fraction(1, n*n-1) for n in xrange(2, 100000)) run("test1()") #end benchmark On my MacBook this reports a total time of 38.072 seconds, with 22.731 of those (i.e. around 60%) being spent in abc.__instancecheck__ and its callees. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1682> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
