----------------
I think a possible alternative way to handle this is to do some sort of 
"unification" for the two values. The current approach is superior in the sense 
that solving and generating constraints are clearly separate. Also this might 
be better for generating useful error messages. In case the solver ever becomes 
a bottleneck, I wonder whether replacing this with a unification step would 
speed things up a bit. 
Although that would only work for the equality case.
