SumType isn't a drop-in replacement for Algebraic (e.g., it 
removes some unsafe methods like `peek`), so it would have be 
included in addition to Algebraic, rather than instead of it.

That said, if Walter, Andrei, and the rest of the Phobos team are 
ok with having two implementations of essentially the same thing 
in the standard library, I think SumType has reached a level of 
stability where I'd be comfortable submitting it for inclusion.
