You may consider this:

ruby-coreの60メール以上のthread(method names in 1.9)の結果の翻訳です:

このいくつかのメールの後の結果は:

1.- Object.send(メソッドの名前)について

.send を使うけど
"send"をしていません。実はそのオブジェクトは命令を受けている。sendの意味はそのオブジェクトは外にデータを送るみたいです。だからいくつかの新しい名前を提案しました:
Object.dispatch(メソッドの名前)
Object.invoke_method(メソッドの名前)
Object.invoke(メソッドの名前)
Object.private_send(メソッドの名前) そうだったら protected_send と public_send も作ります。

それに、そのメソッドはprivate methodを呼べるから 名前に ! を使ったらいいです。

2.- method_missing の使いかた
Rubyの初めの一歩のページを読んだらそのように説明しています： Rubyのメソッドだったら呼ばれていないでいつもメッセージを受けます。
しかし、.method() と .send()が 違います。 .method()と Method.call()は
method_missing
を使いません。send()はmethod_missingを使います。だから、Ruby-coreの人でもRubyのメソッドは
call and messages があるかどうかはっきりわかりません (Ruby だったら .method() == call ,
.send() == メッセージだと思った人もいました
)。.method()と.send()のbehaviourが違うのはちょっとびっくりします。

send to public_send の問題は選んだ名前です。

「Object.send(メソッドの名前）」と言う時、Rubyの意味は：
「Object に向ってメソッドを動かせるように送ります。」

でも、「Object.send」は、英語の自然な意味では：
「Object がメソッドを送ります」
↓
「このObject は自分の外の世界にシグナルを送る。」みたいです。(ところでそのような機能はいい考えだと思います)。

だからObject.send のために他の名前を提案しました。
Object.dispatch( )
Object.invoke( )
この名前はObject ã«æƒ…å ±ã‚’é€ã£ã¦ã„ã‚‹ã“ã¨ã‚’è¦‹ã›ã¾ã™ã€‚
