In other words, I really do just want to get the first item of that list. As I understand it, match is supposed to be used for heterogenous lists where each member has its own semantics. That is not the case here. Obviously, I could write (match ... (x . _) x) but I don't see what benefit that brings. J' -- Avoid eavesdropping. Send strong encrypted email.
