Regex with named capture groups getting all matches in Ruby

Question

I have a string:

s=\"123--abc,123--abc,123--abc\"

I tried using Ruby 1.9\'s new feature \"named groups\" to fetch all named group info:

Answer 1

Piggybacking off of Mark Hubbart's answer, I added the following monkey-patch:

class ::Regexp
  def match_all(str)
    matches = []
    str.scan(self) { matches << $~ }

    matches
  end
end

which can be used as /(?\w)/.match_all('word'), and returns:

[#, #, #, #]

This relies on, as others have said, the use of $~ in the scan block for the match data.
