I think it's to differentiate the different namespaces (scalar, array,
hash) within the match object's hash. Personally, I don't like it, and
think that people should just not do:
/ $var := <foo> , @var := <bar>* /
Because it's dumb.

No. I think you can do this:
/ <hunk>* / # maybe / (<hunk>)* /
$0{hunk}[3]
