As I understood everywhere in `statement.dd` "illegal" means incorrect
statement and it shouldn't be compilable. So "illegal" in `expression.dd` is
expected to do so too.

You reply means for me that those "illegal" statements doesn't compile with dmd
but it is implementation specific and an other D compiler may compile them fine
and it will result in undefined behavior. It will be a hell.

Or am I mistaken somewhere?
