Description (last modified by Vincent Delecroix)

Implementation of a set (using the category framework) from a function that returns an iterator. Building a set directly from an iterator leads to the impossibility of pickling.

A previous implementation in sage-combinat was CombinatorialClassFromIterator? (in sage.combinat.combinat) which is now deprecated.

I'm in trouble with two points:

1) What to do with the equality test when the set are both infinite ? (see in the patch the warning printing on stderr)

2) What is the good way to implement the decorator for a method ? The implementation for functions work quite well but in sage.misc.cachefunc the implementation for methods rather than functions seem more tricky.
