Something like this should do what you want:
timo@schmand ~> perl6 -e 'my $a = gather for ^5 { say "get from a!";
take $_ }; my $b = gather for ^5 { say "get from b!"; take 10 * $_ + 1
}; .say for (|$a, |$b)'
get from a!
0
get from a!
1
get from a!
2
get from a!
3
get from a!
4
get from b!
1
get from b!
11
get from b!
21
get from b!
31
get from b!
41
Hope that helps!
