Assumptions: more informative print for False axiom (Close: #4054)
When an axiom of an empty type is matched in order to inhabit
a type, do print that type (as if each use of that axiom was a
distinct foo_subproof).
E.g.
Lemma w : True.
Proof. case demon. Qed.
Lemma x y : y = 0 /\ True /\ forall w, w = y.
Proof. split. case demon. split; [ exact w | case demon ]. Qed.
Print Assumptions x.
Prints:
Axioms:
demon : False
used in x to prove: forall w : nat, w = y
used in w to prove: True
used in x to prove: y = 0
