- lseq-find pred lseqprocedure
Return the first element of lseq that satisfies predicate pred, or #f if no element does. It cannot reliably be applied to lseqs that include #f as an element; use lseq-find-tail instead. The predicate is guaranteed to be evaluated on the elements of lseq in sequence order, and only as often as necessary.
