You want to include a list in your program. This is how to initialize arrays.
#!/usr/bin/env raku
use v6;
# comma separated list of elements
my @a = ('alpha', 'beta', 'gamma');
say @a[1];
# angle brackes to autoquote items
{
my @a = <alpha beta gamma>;
for @a -> $e {
say $e;
}
}
# vim: expandtab shiftwidth=4 ft=perl6
