It is an anonymous function (lambda) with two
anonymous arguments (_ and __), they are
denoted with underscores so one can see they
are not used - if they were called element-1
and element-2, the byte-compiler will warn
about unused lexical arguments.

Why not just lambda ()? The truth is out there
in the docstring of `sort'.

It's time to take scrambling to the next level:

(scramble-string "Hello there, Emacs is very
cool piece of software")

"aye eposrr lvre olsec,ewfico ceti ftomH hseoa
