[racket] Is there a name for: (lambda (x) (x)) ?

I often wondered why -identity- is not included in the exports of
racket/base.
But which functions would we choose?
(lambda (x) x)
or
(lambda x (apply values x))
which can simply be wrtitten as
values
So -values- may be the identity you are looking for.
