struct bbyte {
    byte b;
    alias b this;
}

void bar(bbyte b) {}

bbyte baz() {
    byte b;
    return b; // cannot implicitly convert expression (b) of type byte to bbyte
}

void main() {
    byte b;
    bar(b); // function bar (bbyte b) is not callable using argument types
(byte)
}

The above code fails on the marked lines as it's trying to convert the byte to
a bbyte. Ref discussion:
