Abstraction over the build-in associative array(one type of

Plese criticize.
Any examples of what this actually accomplishes? Maybe an example
of an algorithm that can do something useful with these
primitives? A rationale for why these are the chosen primitives?
As the proposed "associative range" isn't consumable like other
ranges, this seems more like a specific kind of *container*, not
a *range*; indeed the text of the DIP seems to conflate the
concepts, but they are separate by necessity.
Note that opIndex and opBinaryRight are already container
primitives (see std.container). There's also the additional
relevant primitive `removeKey`. Beyond that though, associative
containers could need some more fleshing out in the container
concept.
As it is, I think this proposal suffers both from lack of
substance and confusing terminology.
