title: Why do hedge funds and financial services often use OCaml?
body: <p>Speaking to a number of quants / hedgies, I came to the conclusion that a large number of them seem to be using either a homebrew language or OCaml for many tasks. What many of them couldn't answer was why.</p>
  
  <p>I can certainly understand why they wouldnt want to use C++ for the most part, but why is OCaml superior for these uses compared to other scripting languages, say Python, Ruby etc?</p>
