I am in favor of documenting them. I don't think we are losing much by 
exposing those types to the user, it seems hard to modify the 
implementation of mpz_t in a way that would break those types without 
breaking a lot of other things. The main question in my mind is how to 
document them so users don't get too confused about what they should use 
and when.
