Let me know (off-list) if you need help in deciphering things in kona.

Yes, this may not simple....

To me a "stream" can be arbitrarily long and may grow while you are
operating on it. For example C's stdin, stdout etc. That means you
can't always operate on a "whole" string all at once as you can
with arrays. But many of the functions that operate on arrays are
useful with real streams. For example, a service may be generating
a stream of request log records. You may want to analyze these logs
for a given time period and may be create a graph. E.g. you may
have a pipeline like
MakeStream(requestLogStream).
StartAt(date1).
EndBy(date2).
GroupBy(requestorIP).
Each(Count).
...
Here GroupBy may generate a stream of streams. Note: I am just
sketching the idea; there are many holes here.
The idea is you can slice and dice these streams in various ways
to make sense of your data. Basically you are building unix like
pipelines but they are typed and you are not constrained by shell
syntax.
This will be non-trivial but can be a very useful package.
