@loke @otini The ecosystem is called #OPAM, it has plenty of bindings for the common C libraries, to start with.
The benefits of #OCaml are most apparent in a project involving some complicated data structures — (G)ADTs and parametric modules are super useful for defining and operating with those structures.
TBH, IDK what to recommend to get started with OCaml specifically, since I myself learned #StandardML first (via the R.Harper's book). But I won't recommend the #Huskell resources either.
