First example that comes to mind is SQL inside Python (I'm actually doing this right now). Say, you've got a raw SQL query in your Django app. To a standard editor, the query is a simple string, however it's absolutely great to be able to mark this string as SQL, getting all the correct syntax highlighting and linting etc. PyCharm already does this, even going a step further, validating the DB schema along the way. Super useful!
