I don't see why you wouldn't be able to use compile-time
information like __traits with the runtime.
In my head, I imagine that at compile-time you can figure out
which unions are in @safe functions, add a UDA to each (so you're
marking data, not code), and then read that information at
run-time (like with __traits).
