Ah, I see. Out of curiosity, is the casetype tactic similar to the elimtype tactic? It looks like the reference manual doesn't say anything about casetype (or maybe I'm just looking in the wrong places).

Anyway, to make the omega tactic solve your goal when hypotheses are
inconsistant, you could do

casetype False; omega.
