Feature #11999: MatchData#to_h to get a Hash from named captures - Ruby master - Ruby Issue Tracking System

class MatchData def to_h self.names.map { |n| [n, self[n]] }.to_h end end p '12'.match(/(?<a>.)(?<b>.)(?<c>.)?/).to_h #=> {"a"=>"1", "b"=>"2", "c"=>nil} Sometimes I want to get a Hash from named capture, but currently I have to use #names + #captures. How about adding MatchData#to_h for convenience way?
