- lseq-find-tail pred lseqprocedure
Returns the longest tail of lseq whose first element satisfies pred, or #f if no element does. The predicate is guaranteed to be evaluated on the elements of lseq in sequence order, and only as often as necessary.
lseq-find-tail can be viewed as a general-predicate variant of the lseq-member function.
Examples:
(lseq-find-tail even? '(3 1 37 -8 -5 0 0)) ;=> (-8 -5 0 0) (lseq-find-tail even? '(3 1 37 -5)) ;=> #f ;; equivalent to (lseq-member elt lseq) (lseq-find-tail (lambda (elt) (equal? x elt)) lseq)
