Pratt parsing is a black box
A blog post argues that Pratt parsing, the widely used technique for handling operator precedence in expression parsers, is treated as a black box by many programmers. The author examines why the method, common in language implementations, is often taught and applied without a clear understanding of how precedence and associativity actually emerge from it.
Why now: Programmers and language designers are debating how deeply the algorithm is actually understood.
