Sounds fine to me, what changes to a standard tokenizer and parser would you make to carry out your plan? I'm not saying this is a shining example of brilliant programming, but it is in a semi-working state and something "in a similar style" (that is, a three-pass tokenizer -> LR parser -> LR parser where scope information and other metadata is computed in the second pass and fed into the third) should be able to handle the changes you're talking about. https://github.com/dbpokorny/autoclave/ https://github.com/dbpokorny/autoclave/
