Pratt parsers are elegant. I really like them. For those to whom they are new: I found them a little tricky to implement directly from Pratt's paper or even Crockford's javascript that popularized them. So, through trial and error I figured out how to actually implement them in regular languages (i.e. not in Lisp). If it helps, examples in C and Go are here: https://github.com/glycerine/PrattParserInC https://github.com/glycerine/zygomys/blob/master/zygo/pratt.... I find them easier to work with than the cryptic LALR(1) bison/yacc tools, but then I never really felt like I mastered yacc to begin with.

S-expressions rule. I use them for configuration everywhere. I wrote a lovely library for parsing them in Go (along with a full lisp interpreter if you like) https://github.com/glycerine/zygomys Provides comments, multiline strings, and automatic translation into Go structs using reflection.

Here's another one: https://github.com/glycerine/zygomys I think he wrote it with a TSDB in mind.

I wish an experienced LISPer would explain why should one use Common Lisp over a language like Golang. Golang now has https://github.com/glycerine/zygomys for scripting. For that matter, why would one choose Common Lisp over GNU guile ? (guile now supports fibers). What does Common Lisp offer for the working programmer that is an advantage over other languages ?

I have been writing one available at https://github.com/archevel/ghoul it is not finished in any way shape or form. I'm currently rewriting the evaluator to do tail call optimization in my spare time and when that's done I'll work on handling macros.
