Well, that is the obvious implementation of cmp(), but that's not the point of 
the package. The package provides a callable class that represents a cmp() 
function. The problem is that it is not just creating some keys and calls 
cmp() on it. I could not find out a way to create a single key.

I guess the right way to port the package is to implement a sort API.
