Ah, much clearer now.

Apologies to Carl if I misinterpreted. I read it as:
"can hardly be blamed for (having) clarity"
;-)
No,
for @array -> $index, $value
{
say "Element $_ is called $value"
}
But I don't understand how the "$index, $value" pair gets its values; is
@array somehow turned into a hash with the index as the key?
With @array -> $index, $value {}, is $_ an alias of $index?
No. There's no

That's a little unfair. Choose good names and it's per
Having read this thread, I tend to think you're insane for bringing it
up again :-)
That said, I'll entertain the discussion for a bit ...

A special variable for when you do a for (@array) style loop
it would always have the index of the array
Discussed on #perl6: it's already quite easy in Perl 6 to loop with an
explicit index:
my @array = ;
for @array.kv -> $i, $v

Or give the block a name (label), and have an index (or several indexes, like
some that are reset by redo an some that are not) avai

Hey do you know what would be cool in perl 6
A special variable for when you do a for (@array) style loop
it would always have the index of the array
Discussed on #perl6: it's already quite easy in Perl 6 to loop with an
explicit index:
my @array = ;
for @array.kv -> $i, $val {
say "$i\t$val
