in thread 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

    Yes.

    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 :-).

    Perl 6 - links to (nearly) everything that is Perl 6.
