Currying would make the Scala API easier to use (and more idiomatic, whatever that means)

[hseeberger]

As an example take the signature of Stream.accum:

final def accum[S](initState: S, f: (A, S) => S): Cell[S]

If this is changed to

final def accum[S](initState: S)(f: (A, S) => S): Cell[S]

users could omit the type argument, e.g.:

val ea = new StreamSink[Int]()
val out = new ArrayList[Int]()
val sum = ea.accum(100)((a, s) => a + s) // was `ea.accum[Int](100, (a, s) => a + s)`

First off, sorry about being unresponsive. I did not get notified that you raised this, for some reason.

I'd be happy to change that. I have quite a few changes that need to be made, and I'll get to those in an overhaul of the Sodium project as soon as I've finished the book, which is pretty soon now.
