Bug #9975: irb で Hash を 1.9 記法で記述したときに、キーがキーワードだと syntax error
https://bugs.ruby-lang.org/issues/9975#change-47938

* Author: 三村 益隆
* Status: Assigned
* Priority: Normal
* Assignee: Keiju Ishitsuka
* Category: 
* Target version: 
* ruby -v: ruby 2.2.0dev (2014-06-24 trunk 46543) [x86_64-darwin13]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
irb で Hash を 1.9 記法で記述したとき、以下の end を伴なうキーワードをキーとして使用するとエラーとなります。

~~~
if do case def for unless until while begin
~~~

エラーが発生するのを確認したのは trunk と 2.1.0 ですが、1.9 以降であれば発生するのではと思います。

添付したパッチを適用すると、上記キーワードをキーにしても正しく Hash として認識されることを確認しています。
