Indeed, many cl-tests default to 'eq.

BTW, what is the reason for this (apart from being a language convention)?

When I try

(let ((start-time (current-time)))
  (dotimes (i 1000000)
    (position '(1) '((2) (5) (2) 2 x  4 fer fer f r e wqf (1) fr r) :test 'eq))
  (format-time-string "%S" (time-since start-time)))

with 'eq and 'equal I get the same result. So 'eq is not more efficent,
is it?
