Hi:

Thanks to everyone for all the left-recursion discussions, I have been most interested.

I had played with a very similar approach, but had not sorted out indirect recursions, so thanks Orlando and I'd be most interested in anything more you have on this.

One nagging worry: my working definition of a deterministic grammar/ parse is that there can only be one match for any rule from any given position... which fits with PEG and pack-rat memos.. but left recursion breaks this definition... Any suggestions?

Thanks again,
Peter Cashin.
