#REPL Below: > my $z = 2,4,6,8; (2 4 6 8) > say $z.WHAT (Int) > say $z.^name Int > say $z.List.WHAT (List) > say $z.List.^name List > With the code above, you might be convinced you've created a $z scalar holding the values (2 4 6 8) that can be coerced to a list whenever you desire. You'd be incorrect though: > my $z = 2,4,6,8; (2 4 6 8) > say $z 2 > say $z.WHAT (Int) > say $z.elems 1 > my $a = (2,4,6,8); (2 4 6 8) > say $a (2 4 6 8) > say $a.WHAT (List) > say $a.elems 4 > say $*VM > moar (2019.07.1) I guess parentheses are important in Perl 6.
