“Today there are several languages in the ML family; the three most prominent are Standard ML (SML), OCaml and F#. Ideas from ML have influenced numerous other languages, like Haskell, Cyclone, Nemerle, ATS,[citation needed] and Elm.[3]”

If you know F#, OCAML, Haskell and scala you can see that the first two have an extremely similar syntax to ML while for the last two the syntax is very different.
