 ``AnyMap``
 ==========
 If you’re familiar with Go and Go web frameworks, you may have come across the common “environment” pattern for storing data related to the request. It’s typically something like ``map[string]interface{}`` and is accessed with arbitrary strings which may clash and type assertions which are a little unwieldy and must be used very carefully.
 This is madness. Hare-brained, stark, raving madness, just *asking* for things to blow up in your face. Unfortunately for people in Go, it’s the best that they can have because of its weak type system; such a thing cannot possibly be made safe without generics.
 Fortunately, we can do better in Rust. Our type system is quite equal to easy, robust expression of such problems.
 The ``AnyMap`` type is a friendly wrapper around a ``HashMap<TypeId, Box<Any>:'static>``, exposing a nice, easy typed interface, perfectly safe and absolutely robust.
 What this means is that in an ``AnyMap`` you may store zero or one values for every type.
 Instructions
 ------------
    make
 Future work
 -----------
 I think that the only thing left for this is filling out additional methods from ``HashMap`` as appropriate.
 It’s a very simple thing.
