I'd say, file an enhancement request on the bug tracker.
However, there comes a point, where given enough indirections, it would
be infeasible for the compiler to figure out exactly where everything
points, and so you'll be able to circumvent the compiler check somehow.
If you're out to thwart the compiler, then eventually you will succeed,
but it begs the question, why?
