Comment:

I have updated the description with the status as of version 7.4.beta0.

Regarding LatticePolytope (one of the examples in the description), I would be reluctant to consider it a finite enumerated set. There should be a distinction between the lattice polytope (an infinite set) and the set of its lattice points. The latter (which also makes sense for non-lattice polytopes) should be made a finite enumerated set.
