Map over new Map(...)

[jasonkuhrt]

I was looking for utilities for working with built in data structures, namely Map. There don't seem to be any? I need a map function, but lots of others could be there too. I understand we can do a map over entries etc. and then create a new map as a result, but, I'm looking for a high level API which is why I come to this library.

Thanks for any consideration!
