I forgot to add this form, which "returns a list":
(receive my-list (imlib:pixel/rgba img x y)
(do-something-with my-list))
It doesn't really return a list, of course, but the pattern-match
creates one for you.

Personally, I find it useful. In this particular example, it makes
less sense -- who wants the red-value without the other values as
well? But there are useful cases for a "primary return value" with
optional, secondary ones.

You can if you wish, but I'll counter-complain. ;-)
