Re: transducers

It's hard to read through the propaganda to see what exactly the interface
is, or what is novel (we've had lazy sequence datatypes in functional
languages for ages, and we've been reifing operation to optimize them on
the fly for ages as well, which transducer.js doesn't attempt). There are
many implementation of lazy sequences in OCaml that allow you to combine
intermediate transformations without rebuilding the whole data-structure,
see for example:
  - batteries Enum module (a bit too featureful for its own good)
https://ocaml-batteries-team.github.io/batteries-included/hdoc2/BatEnum.html
  - batteries Seq module
https://ocaml-batteries-team.github.io/batteries-included/hdoc2/BatSeq.html
  - Simon Cruanes' iterators/generators:

If you have specific needs (for example you want to exactly mirror
transducerjs' interface), you may want to implement something on your own.
You can do something reasonable in one afternoon's of work.
