Fun bit of trivia: Rust was originally implemented _in_ OCaml, and takes a lot of cues from it.

I saw a bit of OCaml code in Rust code-base recently, can you say what it's used for? I know that Rust is self-hosting now, but I swear I saw some .ml files there...

  ~/rust $ find -name '*.ml' | wc -l
  72
  ~/rust $ find -name '*.ml' | grep -v ./src/llvm | wc -l
  0

i.e. there are some OCaml files in a Rust checkout, but they're all part of LLVM, mostly part of the "OCaml Kaleidoscope": http://llvm.org/docs/tutorial/OCamlLangImpl1.html
