I'd have to go digging in old posts, but I'm pretty sure that that's essentially 
how you're supposed to do it in D. I haven't ever done it because I think that 
that sort of casting is pretty evil and only should be used as a last resort, 
but I believe that unions are the correct way to handle it in D. It's been 
discussed before, I'm fairly certain, though I think that the last place that I 
saw it was buried in a topic on a specific problem rather than anything 
necessarily particularly searchable in the archives.
