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. I have never seen any example of spec of this sort of parameters. Let me know the way to describe this spec. | 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? I think they are FMT's forte. Soo -- INITERM
