I hope so; that would be extremely useful. I would like to see an
ECMAScript source - AST parser (as well as an AST evaluator) in the

object, produce a function object from AST, simple AST manipulations,
and so on) will help us (JS developers) tremendously by reducing the
existing hackery, and increasing the performance, while clearing the
road for the

But which language spec? Again, specs only traffic in observable
