Hmm, that seems wrong. Consider:
"xxxyxxyxy" ~~ / [ [ (x) ]* (y) ]* /
I argue that by the structure of that rule, you should be able to tell
which xs go with which y. Currently, the match object comes out:
[0] => [ [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL
PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] ],
[1] => [ [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] ]
Obscuring that information. Whereas, with "deeper" nesting semantics, you get:
[0] => [ [ [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] ], [
[EMAIL PROTECTED], [EMAIL PROTECTED] ], [ [EMAIL PROTECTED] ] ]
[1] => [ [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] ]
Making it easy to tell which xs go with which y ($/[0][1] corresponds
to $/[1][1], etc.).
Is there a counterargument that I'm not seeing?
