自身のハッシュ値を整数で返します。 Data#eql? で比較して等しいオブジェクトは同じハッシュ値を返します。

Data#eql? で比較して等しいオブジェクトは同じハッシュ値を返します。
//emlist[例][ruby]{

Module
# ruby2 _ keywords(method _ name , . . . ) -> nil (12285.0) -
For the given method names, marks the method as passing keywords through a normal argument splat. This should only be called on methods that accept an argument splat (`*args`) but not explicit keywords or a keyword splat. It marks the method such that if the method is called with keyword arguments, the final hash argument is marked with a special flag such that if it is the final element of a normal argument splat to another method call, and that method call does not include explicit keywords or a keyword splat, the final element is interpreted as keywords. In other words, keywords will be passed through the method to other methods.

Proc
# ruby2 _ keywords -> proc (12285.0) -
Marks the proc as passing keywords through a normal argument splat. This should only be called on procs that accept an argument splat (`*args`) but not explicit keywords or a keyword splat. It marks the proc such that if the proc is called with keyword arguments, the final hash argument is marked with a special flag such that if it is the final element of a normal argument splat to another method call, and that method call does not include explicit keywords or a keyword splat, the final element is interpreted as keywords.
