The goal here is to reduce potential confusion between
assert_type(val, typ)
andassert isinstance(val, typ)
.The former is meant to ask a type checker to confirm a fact, the latter
is meant to tell a type checker a fact. The behaviour of the latter more
closely resembles what I'd expect from the previous phrasing of
"assert [something] to the type checker".
