The compiler should either fail to match, since inout wildcard is not applying
to the immutable, or if it does match, it should treat foo as:

int** foo(int **x) { return x; }

This should fail to be able to be called with immutable(int)**.

The assert should fail because the typeof should resolve to Error.

I think this bug is invalid.
