"I like single-line cases. 'cond is ugly because.. the case and consequence onto separate lines."
You know, you're right. I change my mind. The major problem isn't merging lines, it is how to keep things clear when both the case and consequence are long. Just using indent to distinguish them is a poor solution because we use indent to group things together everywhere else.
To see how bad things can get, this definition of markdown is an eyesore: http://github.com/nex3/arc/blob/fe2c9eb2d6/lib/app.arc. Wart doesn't really improve matters except to add the :else to distinguish the two consequences right at the end.
