Presenting the Turducken Type Technique: Certified Evil™

[FeepingCreature]

Oh yeah, two notes.

First: you might say "it's easy to be un at safe if you use 
@trusted." However, the @trusted part is both well-defined and 
positively pedestrian, since we are either targeting default 
initialized memory or just ran destroy() on it (which by the way 
is @safe) so really, if you're holding a reference past that 
*you're* the one doing undefined things.

Second: since I forgot, credit @n8sh on github for pointing me at 
the union technique, though the blame for the current incarnation 
of the trick is all mine.
