Speaking of problems, in my opinions the three biggest are: - Lack of automatic multicore scheduling, this is going to be solved with OCaml multicore project [1] - Lack of updated GUI libraries. There is LablGTK [2], but it stuck to GTK+ 2 version. The main developer started [3] to work on GTK+ 3 version support, but it is still at the very beginning. - Bad Windows platform support [4] (grep for "Windows" word at this page) and [5]. With upcoming opam-2.0 [6] release the support will be slightly better though.
