This should fail for floats, since a[3.14] is a bug. OTOH, int(x) where x is a float should work, and that's where __int__ is used. And int(s) where s is a string should also work, so int() can't call __trunc__ (as was explained earlier in the thread). -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-change-the-world/>
