Pernicious numbers

Straightforward implementation using Raku's is-prime built-in subroutine.

sub is-pernicious(Int $n --> Bool) {
    is-prime [+] $n.base(2).comb;
}

say (grep &is-pernicious, 0 .. *)[^25];
say grep &is-pernicious, 888_888_877 .. 888_888_888;

Output:

3 5 6 7 9 10 11 12 13 14 17 18 19 20 21 22 24 25 26 28 31 33 34 35 36
888888877 888888878 888888880 888888883 888888885 888888886
