"found something else" should say more about what it found

Describe the feature

We can get errors like

Expected expression of type bool; found something else

A developer at the bootcamp expressed a wish for this error to be made more specific, so that it would say more about what it found instead of the expected type. (Maybe there's a reason this is hard because maybe there are some expressions to which it's difficult to assign a unique type.)
