For what it's worth, both Algebraic!(T, void*) and Algebraic!(T, void)
compile on my branch of std.variant.

alias Algebraic!(int,void) nint;

Yes, compiler qualifies null as void*.
I was playing with void* version few weeks ago and I can confirm that
both assignment and equality testing works for nulls.
One thing I missed was lack of conversion to string "null". For example
array of Algebraic!(int, void*) was printed as [0, 0, 2], when element 1
was null. I think it should rather be [0, null, 2].
