Third, http://dev.perl.org/perl6/doc/design/syn/S12.html says:You can also mixin a precomposed set of roles: $fido does Sentry | Tricks | TailChasing | Scratch; Should that be the following? $fido does Sentry & Tricks & TailChasing & Scratch;
If you follow my idea of a type lattice build from roles with | as join and & as meet operator these two mean something completely different. The first is the join or union of the roles while the second is their meet or intersection. The first creates a subtype of the roles the second a supertype. But the typishness of roles is debated.
