Not in this case. An ordered map implemented as a tree has the same interface but with very different operation complexities

My comment was meant tongue in cheek. Maps are _the_ universal data structure: they can be used to map any input to any output. The rest is just an implementation detail.

One might even call them "functions", but that ruins the joke.
