Besides your request is sorta weird (languages are mostly meant to give a ruleset of expressions, not a framework of mutability, at least the more widespread ones), Python does not support something like this out of the box. There have been several discussions about such features and they were all abandoned due to unification. You can, of course, follow the "normal" track to implement any language and write a parser, lexer, compiler and whatever. Tools like `pyparsing`_ or `PLY`_ might help you (there are much more). Though, there *is* a mutable codeset of Python called `Logix`_. As far as I glanced at it, it is pretty mutable and might fit your needs perfectly. Ah, and if you perhaps remove the leading << there, this might be pretty much implementable by overloading __rshift__ at your koristiti object.
