Feature #6802: String#scan should have equivalent yielding MatchData

Ruby should have method to obtain not an array of arrays but of MatchData objects. It can help in obtaining named groups:

pattern = /x: (?<x>\d+) y:(?<y>\d+)/
polygon = []
text.scan_for_pattern(pattern){|m| polygon << Point.new(m[:x], m[:y]) }

Not to break existing code we need unique name. Ideas? May be #each_match
