`rw`: wrong error message

Opened this issue · 1 comments

rw [lemma_wth_typo] with a non-existing lemma yields a wrong error message.

I have no idea about this. If I rename our macro to anything but rewrite or rw, it shows "unknown identifier 'mul_comm'", but as soon as I name it rw that dissapears :(
