Thanks!

But i have no example for this commit.
This commit from [Range#each already gotten the first element](https://github.com/rubinius/rubinius/blob/3c191e31d06b1f1a2082de14dbcdd8ecd306f714/kernel/common/range19.rb#L12-L14).
And this method is not used by other objects.
Prefer private  to protected for me.
