Imagine you’re parsing some JSON. You could parse the JSON into Racket data structures using string->jsexpr, then use match to extract the data into bindings: (match (string->jsexpr some-json-data) [(hash-table ['name name] ['age age]) (list name age)]) This turns out to be enormously useful, especially when combined with other match patterns.
