/**
Map allows key to value mapping for arbitrary value types, and many key
types.
This is a multi-type abstract, it is instantiated as one of its
specialization types depending on its type parameters.
A Map can be instantiated without explicit type parameters. Type inference
will then determine the type parameters from the usage.
Maps can also be created with `key1 => value1, key2 => value2` syntax.
Map is an abstract type, it is not available at runtime.

2. if K is an `Int`, `haxe.ds.IntMap` is used
