instead of adding this test here, add this as a language test as this should
test that a compile error should occur not that we generate plausible code,.

I got the test out on a separate file, however, I'm not sure whether it should
go in language or somewhere else. I kept it in html for now. Maybe all these
tests should move under pkg/js/test/ ?
