[*] is also a meta prefix op
say [*] 4, 3, 2; # 24
But it also looks exactly the same as the [*] postfix combination of
operators
my @a = 1,2,3;
say @a[*]; # (1 2 3)
There is supposed to be one that looks like [**]
my @b = [1,], [1,2], [1,2,3];
say @b[**]; # (1 1 2 1 2 3)
Really @a[*] is
say postfix:« [ ] »( @a, Whatever )
And @b[**] is
say postfix:« [ ] »( @b, HyperWhatever )
---
say *.WHAT.^name; # Whatever
say **.WHAT.^name; # HyperWhatever
