Not only a horrible hack, but a bug, and something you really 
can't rely on working in the future. Especially since this 
behavior is only observed with named unions, not with anonymous 
ones.

I'll also mention section 14.19 2 on the Structs, Unions page 
(https://dlang.org/spec/struct.html):

2. Unions may not have fields that have destructors.

Whether that means it's undefined behavior or the compiler should 
statically disallow it is up for debate, I guess.
