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:

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.
