hi,
i'd like switch to, just like case and typecase do, allow multiple values in the 'value' position of the condition:
(switch (foo) ((bar baz) ...))
So the attached patch checks for the key form being a cons and, if so, expands into a (member value :test test) instead of (test value) form. Of course, this means that your key values can no longer be forms, so this may break existing code. I don't have any code which actually uses a function call in the value form of the clause (and a quick grep over my locally installed lisp libs shows nobody else does either), so i'm ok with the change, but i can understand if others don't agree.
I think I like the idea of a multiple-value-switch, but I'm constantly (well, every 6 months) to remove switch and rewrite it, so I'm a bit hesitant to add more features to it...
Thinking about this. Feel free to kick me to remind me.
