I haven't looked much at Raku since it was Perl6, but for comparison,
here's some Perl 5:
$ perl -E 'say "With ..: ";say grep {/nope/ .. say} 1..5; say "With ...:
";say grep {/nope/ ... say} 1..5;'
With ..:
With ...:

This might be a good place to remind folks that perl6 allows
interpolation of method calls, so there's no need to split up your string
literal like that:
> my $y=("ab",12,"xx"); print "y=$y.join(", ")\n";
y=ab, 12, xx
True
> my @y=("ab",12,"xx"); print "y=@y.join(", ")\n";
y=ab, 12, xx
True

... or, you know ...

y=ab, 12, xx
True
> my @y=<>; say "y=@y.join(", ")";
y=ab, 12, xx
