Get fresh variables for the universe context. Useful to make tactics that manipulate constrs in universe contexts polymorphic.

val constr_of_monomorphic_global : Environ.env -> Names.GlobRef.t -> Constr.constr

Create a fresh global in the environment argument, without side effects. BEWARE: this raises an error on polymorphic constants/inductives: the constraints should be properly added to an evd. See Evd.fresh_global, Evarutil.new_global, and pf_constr_of_global for the proper way to get a fresh copy of a polymorphic global reference.
