Comment:

 In #418 Saizan notes:

 Dependencies of the form "foo > x" don't really make sense given the
 hackage version policy, since they exclude x but include x.y which is
 supposed to have a similar api, and if you want something introduced in a
 minor (or lesser) release you can explicitly mention that.

 Also what is often intended with that notation is foo >= (x+1), causing
 confusion.

 I propose that we allow only closed lower bounds, i.e. foo >= x.
