The OCaml backend for the BEAM was called Caramel but has been abandoned after his author went on working on hiw own build system, warp.

Build systems come for our best and brightest. :-(

Talk to your friends and family.

Actor model is a small component of the BEAM. Even then, it guarantees yields to the scheduler.

This is practically impossible to retrofit on to an existing language, esp. in the presence of loops.

GC precludes OCaml from replacing a chunk of those.

>>> don’t think there is a BEAM compiler backend yet

I think there's something close - https://caramel.run/manual/

The project has been abandonned : https://github.com/leostera/caramel/discussions/102
