Re: [Caml-list] CSE with FLambda?

[Mark Shinwell <mshinwell@janestreet.com>]

This doesn't happen at the moment.  We have it on our roadmap for
OCaml 4.05 (freeze around January 2017) to implement some form of pure
function application lifting and sharing, of which this is an example.
We also plan to consider introducing some notion of "function body"
(disentangling them from closures) so that we can automatically
deduplicate functions in general.
