What I'm wondering is how the list knows to feed two items into '[+]'. While 'infix:<+>' must accept exactly two arguments, '[+]' can accept an arbitrarily long (or short) list of arguments.
I thought that at first too, then remembered a discussion about generalizing the meaning of square brackets and how &[op] fell out of it automatically to take a reference to an operator without using the infix:<op> syntax.
