bool is a subclass of int that overrides only the constructor, __str__ and
__repr__ methods.

Provided you don't convert it to string via str() or repr() first before
using it as a dict key, yes.

>    print "There %s %d item%s." % (x[n <> 1], n, y[n <> 1])

> Will the behavior be backword compatible and equivalent or not? Simple
