Thank you! I was actually looking for something specific about parse trees vs S-expressions. That would be https://github.com/c3d/xl/blob/master/doc/HANDBOOK_1

Thank you! I was actually looking for something specific about parse trees vs S-expressions. That would be https://github.com/c3d/xl/blob/master/doc/HANDBOOK_1-syntax.md https://github.com/c3d/xl/blob/master/doc/HANDBOOK_1-syntax.... But I'm reading the whole thing now. Very interesting language! I don't see myself using it in production any time soon, but it looks like a wonderful tool for programming languages research. Thank you again!
