1. Support a :TEST arg for (E)CASE.
I'm not sure what this buys you over a regular cond. Case primarily exists for efficiency, no?
Hi Pascal, I see your point _but_ there is also something to be said for efficiency of human code reading and code writing, no? I'd say that case variants let the reader know that all of the tests are of the form "this" is the same as "that" for some notion of "same as" and various "that"s. (case <this> (that-1 ...) (that-2 ...) ...) whereas cond is saying, do an arbitrary test for each possible branch... This may not be enough to argue for adding to / extending case... cent, cent, -- Gary Warren King, metabang.com Cell: (413) 559 8738 Fax: (206) 338-4052 gwkkwg on Skype * garethsan on AIM
