Subject: What is the equivalent of C++ "this"?

I want to write a method within class Array that will put single
quotes around every element of the array.

"this" doesn't work in Ruby.  If it did I would write

class Array
    def quote
        length.times {|i| this[i] = "'" + this[i].to_s + "'"
    end
end

Ruby doesn't know what I mean when I say "this".  How do I call the []
operator when I'm in the array class and have the language realize I'm
not building a list?
