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

some that are reset by redo an some that are not) avai
