I'm having a little trouble understanding locking and unlocking. Is there a way that I can set an option so that [ffun f x => x] a reduces to f a upon simplification, so I don't have to use the command ffunE every time? Or can I mark a specific finfun as unlockable?
Is this something to do with the phantoms in the first 20 or so lines of the finfun file? I am having trouble making sense of that code
unlock tactic not work?
rewrite ffunE ?
Both unlock and rewrite ffunE work here.
I'm looking for something where I don't have to do this manually, though. Is there a way to get ([ffun x => t] y) to simplify to t[x/y] when the simplification command /= is called?
rewrite allows customizable "variants" of
/= that are almost as short
there's even syntax usable inside
