but then you don't get list assignment semantics for that last line, so it'll parse as ($vector = 1), 2, 3, 4, 5; > Doesn't work for me :-( For me the last statement gives "12". which version of Rakudo are you using?

So you'd have to mess with the STORE method of *all* scalars > (i.e. not just the Vector() class) ? No. Just those that you want to behave specially. And I never recommended it. Cheers, Moritz
