use MONKEY_TYPING; augment class Mu { method FOO(Mu:U:) { say 'Mu.FOO'; } } augment class Str { method FOO(Str:D:) { say 'Str.FOO'; } } ('a' & 'b').FOO(); Output: Parameter '' requires a type object, but an object instance was passed in method FOO at dispatch.pl:3 in block <anon> at dispatch.pl:14 in <anon> at dispatch.pl:1 I'd argue that since the FOO method in class Mu fails to type-check against the argument list, the other candidate should be considered for autothreading. I believe (though I can't prove it) that this is the real problem behind https://rt.perl.org/rt3/Ticket/Display.html?id=103106 (regex-matching on a junction fails)
