test-group and test-group-with-cleanup also need to be macros,
because they can also be skipped.

test-with-runner also needs to be a macro, but it's a convenience
form, not primitive.

I think that works and seems to make sense.

I.e. the specification should clarify that the test-name
is an expression that evaluates to string, not necessarily
a string literal?
