Since the reducer concept has been established before transducer, I
think you can just skip the 'reducing function... in the list below
called simply "reducer"' part and call all of them reducers.

The part about "due to how the transduction is built it is applied
left to right", is it possible to just reverse the order of arguments
internally in 'compose' or is there a good reason to keep it this way?
I haven't read the implementation so I might be missing something.
