I'm concerned because this means we're no longer testing any behavior at all in
spec mode.  What happens in spec mode?  If it's different from strong mode, I
think we should just change this test so that it asserts the correct behavior
based on what mode it's in.

The behavior is consistent with other *infer* tests. The EntityRef for
inferredReturnTypeSlot in non-strong mode is null, because inference happens
only in strong mode. The name of the test is no consistent though.

Ah, sorry--I missed that detail.  Thanks.
