F# is extremely similar. To put it in perspective how similar, I just ported a project for work over from F# to ocaml in a few days - mostly adding "in" for let blocks and parenthesizing nested match blocks where necessary, and replacing data structures with their ocaml equivalent. Large chunks of that code base didn't require any modification - I'd drop a 500 line source file in, run it through the ocaml compiler and have to deal with a handful of syntax tweaks to make it go through.
