What is the best approach to destructuring strings using predicates? For instance "match a substring for which `string->number` is true."
I can approximate this using `regexp-match-positions` and stepping through possible substrings, testing until one matches, etc. But I notice that this amounts to treating a predicate as an atom. Since atoms like '\\d' and '\\w' are pretty much predicates in disguise, it made me wonder if there were a way to atom-ize an arbitrary predicate. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
