Difficulties with std.variant.Algebraic

Recently Walter has proposed a small improvement able to reduce 
the size of that template. I don't know where Walter proposal has 
gone in the meantime, as people have suggested a better and more 
general design.

Algebraic is still primitive, but improving both D and Phobos it 
can become better. It requires some discussions, design, and 
implementation work.
