title: How can I load a ml file in toplevel of OCaml, just like `use mine.sml` in SML/NJ?
body: <p>In <code>SML</code>'s <code>repl</code>, you can just type <code>use whatever.sml</code> and load all things inside that <code>.sml</code> into <code>repl</code>.</p>
  
  <p>How can I do that in OCaml?</p>
