Subject: [Caml-list] Question about Optimization

Hello --

I'm wondering if there is any work (and interest) on supporting
user-defined optimizations similar to GHC's rewrite rules in the Ocaml
compiler. For example, a standard example would be specifying map fusion:

map f (map g ls) = map (fun x -> f (g x)) ls

This works well in Haskell due to laziness and (mostly) purity but things
are obviously more complex in Ocaml since you can not pretend that things
are pure (due to exceptions, references, IO, and non-termination).

On a related note, this sort of optimization could require a reasonable
amount of static analysis for effects (or trying to reflect effects in the
type system). Has there been any work related to this?

Thank you.
