This sounds very similar to my goal in python to allow a string to be passed to eval() and parsed using an external parser. Thus, it is definitely something we will eventually support. However, right now external parsing can only be done before the program begins to execute, which is probably not good enough for you. Sorry.

Hy Joshua,

Could you give as a little bit more details of what you want to do and where is your problem? I don't really understand where you are stuck.

I'm trying to implement the regular expressions in _javascript_. To do this, I need to be able to take the "a*b" from new RegExp("a*b") and turn that into an internal AST representation of the regular _expression_. I have an external parser which can produce an AST of the regular _expression_, but I don't know how to get K to call this external parser and get an internal AST represntation back.
