If you want an ordered map, then use std.container.RedBlackTree. It's a little 
bit annoying to use as a map (you basically have to use it as a set of 
pairs/tuples which are ordered on their first member), but it's quite doable 
(and is what C++'s STL does internally with std::map). Chaining them like you 
seem to be trying to do though would probably get ugly though.
