in thread How A Function Becomes Higher Order

Let me continue by pointing out that in Perl 6 you would not write max as a list operator or function. Rather, write it as an infix (2-argument) function, and the system will automatically generate the matching reduction operator. Or, write the reduction operator yourself if that's more efficient, but use the reduction syntax:

sub infix:<max> (::Type $left, Type $right --> Type) { return $left after $right ?? $left !! $right; } sub prefix:<[max]> (::Type *$first, Type *@rest --> Type) { ... }
That leaves off the details of how to make it a chaining operator (I guess max chains through normal association) and declaring its level of precedence and associativity, etc.
