Description

I wonder if we can deprecate each_with_index and each_with_object and fully recommend with_index and with_object instead.

I personally like the shorter forms because they hint that they can be used with more methods than simply each. People don't need to ask if there's a map_with_index method, they can just try chaining it the same way and it works! I realized this when teaching new Rubyists, because they often ask those questions.

There is a negligible performance hit.

Lots of code uses each_with_index but it is a one-character change to use each.with_index instead.

Forgive me if this has been brought up recently, but I couldn't find any discussion on it.
