I'm thinking of a slightly different course for std.container. Instead 
of defining an OrderedMap structure that doesn't specify its 
implementation, std.container will define _explicit_ consecrated data 
structures, such as BinaryTree and RedBlackTree (Steve Schveighoffer 
graciously contributed his R-B tree implementation). Later on, we might 
define a set of generic aliases for typical container choices, but I 
want std.container to actually reflect the interesting personalities and 
tradeoffs that data structures have.
