Yes, that's basically it. A minor difference: CL:FIND returns the first matching element, so it's more like (first (drop-while (partial not= x) some-col))), but that doesn't really matter, because there are fundamental differences in design anyway. Things like: (find 1337 list :key #'cadr :test #'id) would be done differently in clojure, and also in CL one should probably structure ones code differently, but in the heat of the battle there are sometimes situations where this stuff might be handy (at least in my case). The problem was not the implementation, but I didn't understynd why something akin to member/find is not part of the core language. "Sufficiently ugly" surely is well put; having read the post linked above made me understand the reasoning behind it.
