This sounds quite a bit like Objective C.

  Objective-C's object model is very heavyweight. Granted, that's what I used to like about it (I haven't worked in it in years). You got to have this very high-level object-oriented language with all sorts of delightful features such as dynamic dispatch, duck typing, and even monkey patching. But you also got to have straight C sitting right there in the same language, and could easily flip back and forth between the two without incurring penalties that TFA mentions such as losing context at a language boundary when you're trying to debug code.

    I don't think it's fair to call it heavyweight. It's both high and low level at the same time, which is part of its awesomeness (there are no "methods" -- only messages (symbol names) so you can send objects messages (dynamic, has an overhead) or use a message to get a hard reference to a function pointer ("selector") and call that directly with no overhead (beyond a function call). So you can be nearly as dynamic as JavaScript or Python, or as performant as C without changing languages.
