--- Comment #3 from kinke <kinke at gmx.net> ---
I bet that PR just uncovered another issue, and the relevant questions IMO are:

a) Why is there a cast in the 1st place? When removing the `ref`, the
`-vcg-ast` output reveals a silly

inout pure nothrow @nogc @safe void locate()
{
    inout(Cell)* cell = null;
    this.getCell(cast(inout(Cell)*)cell);
}

b) Why aren't the 2 types equivalent, where CastExp.isLvalue() would return
true?
