まつもと ゆきひろです

ruby-extから持って来ました。

要するに1.5系で多重代入の右辺をto_aで変換しなくなったが、
to_aryがあればそれを使うようにしてはどうだろうか、という話で
す。確かに

  * to_hash, to_io, to_strなど他の基本データ型には「その型に
    見せかけたいときに使う」ための内部変換メソッドがある。

  * 実は配列のためのto_aryは他の局面ではすでに使われている。
    たとえばArray#replaceは左辺が配列でないとき、to_aryで配
    列化することを試みる。

ことからto_aryを使うのは自然に思えてきました。リリース直前の
変更ではありますが、賛成してくださると幸いです。

あえて今からの変更を強く要望するわけではありませんが、反対意見がな
ければ、to_aryは入れても良いように思います。
