Re^2: I should've known better!

In Perl 5 my $var; ... for $var (...) {...} doesn't alter the contents of the $var global to the for loop. Is that true for both the -> and <-> variants of the Perl 6 for loop illustrated above?

I presume you can for @array <-> my $var {...} in Perl 6 to make the scope of $var obvious.

True laziness is hard work

In Perl 5 `my $var; ... for $var (...) {...}` doesn't alter the contents of the $var global to the for loop. Is that true for both the -> and <-> variants of the Perl 6 for loop illustrated above? Yes. presume you can `for @array <-> my $var {...},` in Perl 6 to make the scope of $var obvious. No, you can't. Both arrows actually introduce a signature, and `my` in a signature doesn't make sense. I used to write `-> my $x` too, but got used to omitting the my rather quickly :-).
