Apologies to Carl if I misinterpreted. I read it as:

No, yours is the correct

No. There's no such magic. I simply screwed up. I should have written:
for @array.kv - $index, $value {...}
:-(
Ah, much clearer now. g

Yobert Hey do you know what would be cool in perl 6
Yobert A special variable for when you do a for (@array) style loop

Discussed on #perl6: it's already quite easy in Perl 6 to loop with an
explicit index:
my @array = moose

I suppose doing a map or a grep over @array.kv is possible:

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 ...

That's a little unfair. Choose good names and it's perfectly

Nah, I was just joking;
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 such
14 matches
