valid metaprogramming?

http.rb

class HTTP
  def request(method, options)
    # stuff...
  end

  [
    :get,
    :head,
    :put,
    :post
  ].each do |method|
    define_method method do |options|
      request method, options
    end
  end
end

Here are my thoughts. Obviously as a sketch I may be missing something you have in mind, but let me know.
