[Feature Request] Pratt Parsing combinators

[stefnotch]

Implementing pratt parsing (or precedence climbing, which is supposedly the same algorithm) could be useful. I quite like it for parsing mathematical expressions with lots of different operators, since I no longer has to bend my parsing rules to fit, and can instead specify the binding power and associativity.

There are other libraries that have implemented this, for example

• https://github.com/kevinmehall/rust-peg#comparison-with-similar-parser-generators
• rust analyzer https://matklad.github.io/2020/04/13/simple-but-powerful-pratt-parsing.html
• chumsky has an experimental one

Thanks, then I'll close this one
