The macro used to return NULL if input was NULL or had the wrong type. Now it asserts that input is nonnull and it has the expected type. There are a few places where a missing or mismatched type was OK, but in a majority of places, we would do both of the asserts. In various places we'd only do one, but that was by ommission/mistake. So moving the asserts into the macro allows us to save some lines.
