Description
In TR, all these functions take an Integer argument. In Racket, however, these arguments are limited to exact-nonnegative-integer?. So the TR types can be tightened to either Nonnegative-Integer or I assume Index (since they pertain to list indexes).

Research direction
Locate the Typed Racket definitions for take, drop, split-at, take-right, drop-right, and split-at-right, then compare their argument types with Racket's exact-nonnegative-integer? requirement. The work is done when these functions accept the intended nonnegative integer type rather than Integer.
