You're welcome. Yes, tools like `new Function(...)` offer tremendous possibilities. Since the beginning!

One thing I am missing in JavaScript is a (possibly standardized) access to the underlying parser. If I remember correctly, Python offers it. That would make code manipulation much cleaner and easier, without having to use ugly RegExps or maintain parser code.

Another possible direction would be D's mixins (template mixins and string mixins). In practice, that would a bit like `new Function(...)` but keeping access to the local context, which would be... like... the One Evil Thing.

Feel free. If you find something faster, I'd be happy to update code & results.

Best regards,
