Interestingly, both D and Go have had associative arrays built in to the 
core language. But D now has enough expressive power that the AAs are 
moving into the library, with the barest syntactic sugar left. 
Similarly, complex types are moving to the library, typedefs, etc.

Go realized the importance of immutable strings, but didn't generalize 
that to having any other immutable types.
