I can't help feeling that there's an end-weight problem here: The fact
that it is a test is the essence of statement.
If we're thinking of it as a library, then the MMD way of thinking might
be appropriate: we know it's an equality test so there's no need to
introspect it.
But if we're thinking of it as a core language feature, then using macro
semantics -- and introspecting the AST -- isn't necessarily a bad thing.
It also depends on the context. If we're in a file that contains just
tests, then there's nothing unexpected about seeing a test. Indeed, the
fact that a statement is a test is no longer important (so no end weight
issue). But if we want to see these ":ok" tests littering everyday code
(i.e. as assertions) then it would be wrong to not make explicit the
fact that the statement is a test
