It can...

class Array
  def map(sym=nil, &block)
    self.inject([]) { |col, item|
      if block_given?
        col << block.call(item)
      elsif not sym.nil?
        col << item.send(sym)
      else
        col << item
      end
    }
  end
  def map!(sym=nil, &block)
    self.replace(map(sym, &block))
  end
end
