D claims to follow C, so using unions for type punning is
ultimately implementation defined.
I am not sure if D is the same as C regarding this.

Maybe, but I think the union is a bit nicer because then the
compiler is responsible for more of the details. For example, it
should work with class objects without the complication of
dealing

The cast(void*) isn't necessary.

ahh of course! lol :)

Actually even the cast is unecessary, just use a uniform.

It is non-portable, since some hardware architectures may use
different
