Hello,

  Wow. Great tallyup version.You rock (ruby). As always thanks for
posting / sharing.

   For reference here's my test answer using the sportdb text library / gem.

def tallyup( matches )
  require 'sportdb/text'

  # step 1: convert match array to match "struct / named tuple"
  matches = matches.map do |match|
    team1          = match[0]
    score1, score2 = match[1].split('-')
    team2          = match[2]

    SportDb::Struct::Match.create(
      team1:  team1,
      score1: score1,
      score2: score2,
      team2:  team2
   )
  end

  # step 2: tally up standings
  standings = SportDb::Struct::Standings.new
  standings.update( matches )
  ## note: for the black box "magic" see
https://github.com/yorobot/football.csv/blob/master/sportdb-text/lib/sportdb/text/structs/standings.rb#L175

  # step 3: convert to array of arrays
  recs = []
  standings.to_a.each do |l|
    recs << [
       l.team,
       l.played,
       l.won,
       l.drawn,
       l.lost,
       l.goals_for,
       l.goals_against,
       l.pts
    ]
  end
  recs
end


  Merry Christmas. Happy New Year. Prosit 2019! See you in 2019. Cheers. Prost.
