That's not all that's not supported. Through poking at the live demo, I've found that at least slots, kw-only args, some basic syntax elements, decorators, generators, generator comprehensions and async are additionally not. Exceptions are marked as supported … but `raise Exception()` is a syntax error? (Re-raise and binding exceptions also fails to parse.)
