Hi,
I don't know if I understood your question correctly; I tried two
alternative ways to assign Nil using the REPL:
[0] > my ($a, @b, %c, &d)
((Any) [] {} (Callable))
[1] > [$a, @b, %c, &d] »=» Nil
[(Any) [] {} (Any)]
[2] > say "{$a.^name} {@b.^name} {%c.^name} {&d.^name}"
Any Array Hash Callable
[2] > [$a, @b, %c, &d].map: { $_ = Nil }
((Any) (Any) (Any) (Any))
[3] > say "{$a.^name} {@b.^name} {%c.^name} {&d.^name}"
Any Array Hash Callable
