For what it's worth, I disagree. I think Bool..2 should be equivalent to 0..2 (since Bool is a type object, which numifies to 0). Possibly with a warning, since something undefined is being numified. Patrick pointed out on #perl6 that infix:<..> cannot be meant to numify by default, because then 'a'..'z' wouldn't work. But either of these options would still be viable: * If the rhs is Numeric, numify the lhs. * If either the lhs or the rhs is Numeric, numify the other one. I haven't come up with a use case to show that one of these options is better than the other. The first is a bit reminiscent of smartmatching; the second is more symmetric. I don't think Range should be a role. I don't have any rational argument, just the feeling that it's something of a premature type restriction. // Carl
