title: Is it possible to import another language with grammar-kit?
body: <p>I am working on a custom language support plugin for Kivy in PyCharm and I think I will need to import some python expressions into it, since .kv files allow some python code in properties definitions and on_properties callbacks definitions.</p>
  
  <p>Is this necessary? How about possible? And how would I go about doing that?</p>
