This should be detailed enough that a conforming implementation could be completely created from this description. I don't think that is true of the current specification. Regardless, allowing arbitrary order and arbitrary omission of arguments seems an especially fragile way to specify a procedure. This is why you have to stipulate things like: "<depth> or <count> can be defined only after <width> is defined." If we add more parameters to fmt this problem will blow up, quick. Why does fmt have two very distinct behaviors? Why not have two distinct procedures? Why have a <show> parameter when you can just apply that function to fmt's result? And further, why are you allowed to pass in only display or write? Why have <string> parameters when you have string-append? David
