Subclassing Array from Enumerator

Description
It often happens that I want to use a method from the Enumerator class on an array, and so I frequently use Array#to_enum. Since Array and Enumerator share the same parent Enumerable, they should be very close. I think it would be convenient if Array inherits from Enumerator. (Perhaps the same thing can be said for Hash too)
they should be very close
They are very close:
Enumerator.instance_methods - Array.instance_methods
# => [:with_index, :with_object, :next_values, :peek_values, :next, :peek, :feed, :rewind]
Which method(s) in there do you claim to use frequently?

I use with_index and with_object frequently.
I use with_index and with_object frequently.
Any reason why you wouldn't simply use each_with_index and each_with_object?

I want to provide an optional starting number (most often 1) to the former.
But you are making me realize that my motivation for the proposal is getting weaker.
I should use each_with_index and each_with_object as marcandre suggests. I withdraw this. Please close this issue.
