It'll want to go through a few polish iterations before I even 
think of doing that; and it'll need support for things like 
toString/toHash/etc.

Another critical bit of functionality that std.bitmanip provides 
that I currently don't is a bit array. I also want to support 
statically sized bit arrays, Phobos only provides support for 
dynamically sized.
