This patch adds a small but useful check to `e(tac)`: detecting seemingly identical variables that in fact have different types. ``` # g `f (x:num) = f 1`;; Warning: inventing type variables Warning: Free variables in goal: f, x val it : goalstack = 1 subgoal (1 total) `(f:num->?142774) x = (f:num->?142774) 1` # e (SUBGOAL_THEN `x = true` ASSUME_TAC);; Exception: Failure "var x appearing with different types: bool vs. num". ```
