  arg1 // evaluates to a unary function
  arg2 // evaluates to a binary function
  arg3 // evaluates to a ternary function

I am surprised.  Shouldn't arg1 be a one-or-more argument function
that returns its first argument, and arg3 be a three-or-more argument
function that returns its third argument?

Also, I think you can drop "evaluates to" and put something more
descriptive in the comments.
