Well, infixes are necessarily binary, but while prefixes tend to be slurpy, I was thinking one could also declare a prefix op with a finite arity. And does [...] only reduce if what's inside is an operator? How do you do a reduce using a plain old binary subroutine? -- Mark J. Reed <markjr...@gmail.com>
