We're still very much interested in this, although I think the challenges
are more important than what you expect. The duality pointer/integer in
OCaml's runtime is a major pitfall. Triaging between both by looking at the
least significant bit won't be easy to handle.

In any case, if somebody looking for an internship is interested by this
topic, you're more than welcome to contact me!
