title: Open and execute file in SML interpreter from within Vim
body: <p>I've been using vim for editing code for some time and now I want to use it effectively for programming in Standard ML. In emacs one can use sml-mode which allows one to open the SML intepreter (Moscow ML in my case) in a buffer and load the actual file.</p>
  
  <p>Is it possible to run the Moscow ML interpreter and load the actual file from within vim?</p>
