じゃ、弄ばれてた？(^^;

いや、あくまでInteger#fmtです(Integerの文字列表現は様々で
to_sでは対応しきれないからとういのが根拠だったんじゃなかった
かな。きっと)。

Pythonからの転向組はうれしかったりするんですかね？
演算子が自明かどうかっていう話しは結構難しそう。

# IO#<< って自明？


ところで、数値を3桁ずつに区切るための正規表現って

  s = "1000000000"
  while s.sub! /([^,])(\d\d\d(,|$))/, "\\1,\\2"; end
  p s

よりも、もっと簡潔(?)なモノがありませんでしたっけ？
ごとけんさんがやってるようなreverseしてreverseが悪いというわ
けじゃなく興味本位で。
