[ruby-core:47059] [ruby-trunk - Feature #6802] String#scan should have equivalent yielding MatchData

Issue #6802 has been updated by tomoakin (Tomoaki Nishiyama).


+1 to have a method to return MatchData.
This is related to (or duplicate of) #5749 and #5606. 

Even with the simple implementation I think to establish a standard
name and specification.

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
