### Lists

The SRFI-1 List Library is available, though not enabled by default. To use its functions you must `(require 'list-lib)` or `(require 'srfi-1)`.

         (require 'list-lib)
         (iota 5 0 -0.5) ;; => (0.0 -0.5 -1.0 -1.5 -2.0)

reverse! list | Function

The result is a list consisting of the elements of list in reverse order. No new pairs are allocated, instead the pairs of list are re-used, with `cdr` cells of list reversed in place. Note that if list was pair, it becomes the last pair of the reversed result.
