Amazingly, this even speeds things up. 

# old
sage: timeit('[h(1,2) for h in T.to_cartesian(operator.mul)]')
625 loops, best of 3: 968 µs per loop
# new
sage: timeit('[h(1,2) for h in T.to_cartesian(operator.mul)]')
625 loops, best of 3: 939 µs per loop

Good work, sorry it took so long to get to reviewing this.

Annoyingly, all these doctests are not visible in the built docs because the entire class is an underscore!
