Test for subject reduction, as in Carneiro's thesis.

The annotation on the lambda writes the middle term of corner-cases/alg-conv-trans-acc down by hand, sparing the kernel from having to invent it. The body checks against right, the argument against left, and the two endpoints are never compared.
