/**
 * I LOVE :echo
 * I LOVE :js
 *
 * 説明
 * :echo コマンドが大好きな人用
 * とにかく、ワンラインでタブ補完しつつコードを実行するためのネタ的プラグイン
 *
 * 完成度は低い
 *
 *  設計思想
 *   *  最初に与えた引数を変換に変換を重ねてコネくり回すことが主眼
 *   *  各メソッドやgetterは常にvalue(またはxhr)メンバを持つObject
 *   *  メソッドやgetterはvalue値に相応しいメソッドまたはgetterである
 *
 *
 * Example:
 *        1                                        2      3      4   5        6           7                              8
 *  :echo $x("http://d.hatena.ne.jp/teramako/rss").open().send().xml.toObject.get("item").map(function(item) item.title).value
 *  ブログのRSSをゲットしてオブジェクト化して、各item要素内のtitle文字列を格納した配列をechoする
 *
 *  1. $xにURLを渡し
 *  2. XMLHttpRequest.open()し
 *  3. リクエストを送信し
 *  4. レスポンスをDOMオブジェクトを得て(XMLHttpRequest.responseXML)
 *  5. さらにObject化し(toObjectはXMLのタグ名をキーにツリー構造を模したObject)
 *  6. オブジェクト内の"item"メンバ(配列)を得て
 *  7. map関数で各item内のtitleを得て
 *  8. その値 :echo に渡す(RSSのタイトル一覧の出力となる)
 *
 *  :js $_.url.MD5Hash.copy()
 *  現在開いているURLのMD5ハッシュ値をクリップボードにコピー
 *
 *  :js $x("http://example.com").open().send().xml.stack()
 *   とりあえず、http://exapmle.comのDOMドキュメントをstack
 *  :echo $_.cache.last.inspect()
 *   最後にstackしたものを取り出し、DOM Inspectorが入っている場合はDOM Inspectorに出力
 *
 *  :echo $('//a').evaluate().grep(/^http/).join("\n").copy()
 *  リンクを抽出してクリップボードにコピー
 *
 *  :echo $('//a').evaluate().map(function(v)v.href.replace(/.*\//,'')).copy()
 *  :echo $('//a').evaluate().map($f.href().replace(/.*\//,'')).copy()
 *  リンクのファイル名部分のみをクリップボードにコピー
 *
