That's precisely what CombinatorialFreeModule elements are :-)

Further optimizations to it are most welcome (For example, I am not
sure += is implemented there)!

Yes, the name is bad: there is nothing combinatorial to it. Merging
this into FreeModule so that one could do FreeModule(QQ, Objects()) is
part of the future plan.
