Golfed even further:
09:44 < moritz> nom: multi a($, $) { }; say &a.arity
09:44 <+p6eval> rakudo 4235df: OUTPUT«1»
Seems the arity calculation is generally a bit off

09:38< moritz> nom: say&infix:<~>.arity
09:38<+p6eval> rakudo 4235df: OUTPUT«1»
09:38< moritz> nom: say&infix:<~>.count
09:38<+p6eval> rakudo 4235df: OUTPUT«1»
09:38< moritz> ah, that's wrong
09:39< moritz> nom: say&infix:<~>(2, 3)
09:39<+p6eval> rakudo 4235df: OUTPUT«23»
This leads to @list.reduce(&infix:<~>) failing, because reduce thinks it
got an unary operator.
