Hi all. I have a pretty basic question and feel I'm missing the obvious: Which tactic would solve x = ?y
but not f x = f ?y
? A plain simp
will do both, a plain clarsimp
won't do either. I have to be cautious with premature instantiation of schematics, but where the goal is an equality of a schematic, instantiating it according to the equality seems safe and unavoidable to do.
Wild guess: (fact refl [of x])
.
