-----------------------------------------------------------------
Right! The output is always the same : a key and a value.
By the way, the input is quite similar too : a key and a value, except that in
the case of the reducer the value is typed as a list of values.
But that would not worth the effort to render it generic, would it?
Mapper : f(a,b)=>list(c,d)
Reducer : f(a',list<b'>)=>list(c',d')
