This is dmd issue.
Fixing bug5020 is incomplete, so property function + alias this is not
implicitly convertible to bool.

----
struct Rebindable
{
    Object obj;
    @property const(Object) get(){ return obj; }
    alias get this;
}

Rebindable r;
if (r) assert(0);
r.obj = new Object;
if (!r) assert(0);
