Comment (by SimonKing):

 I see no gain in the (not posted) patches I tried. Even though certain
 type errors are raised a couple of hundred times, it is still not
 noticeable if we save "a couple of hundred times 1ms" in a computation
 that takes a couple of seconds.

 Do you have a striking example, in which computing a string representation
 for creating an error message really hurts?
