Description

It would be great if check-equal? accepted multiple values in each of its sub-expressions and then just made sure that they had the same number of values and then checked that they were equal. I usually work around this by writing something like:

(check-equal? (call-with-values (lambda () (call-my-multi-valued-function)) list)
              (list 'the 'expected 'results))

Contributor guide

Research direction
Modify the 'check equal?' function to accept multiple values by using 'call with values' and comparing lists of values. Look at the current implementation of 'check equal?' in the rackunit source and adjust the argument handling.
