Subject: [ruby-core:43446] [ruby-trunk - Feature #1873] MatchData#[]: Omits All But Last Captures Corresponding to the Same Named Group


Issue #1873 has been updated by trans.


This is the first time I've seen regular expression groups, so it's interesting.

It occurs to me that with this addition MatchData is both a sort of Array and a sort of Hash. That being so consider `md.to_h`.

 I suspect that MatchData#[:symbol] should return an Array of values when the same named group has been matched multiple times.
 
   >> m = 'food'.match(/(?<f>oo)(?<f>d)/)
   => #<MatchData "ood" f:"oo" f:"d">
   >> m[:f]
   => "d"
   >> m.to_a
   => ["ood", "oo", "d"]
=end
