If that's what you mean by "no state", then I misunderstood, but I don't especially care what you call a namespace for static functions. (A module?) I use immut

If that's what you mean by "no state", then I misunderstood, but I don't especially care what you call a namespace for static functions. (A module?) I use immutable objects frequently, and they're a different thing, just as first-class nested functions are a different thing from standard C functions.
