Subject: Dynamically Create Singleton Method

I'm not sure how to explain what I'm looking for so I will show you:

# this works, but not quite the functionality I need

def simulate_cgi_upload
  class << cgi_file = Tempfile.new('simulate-cgi')
    def content_type() 'image/jpeg' end
  end
  cgi_file
end


# this does NOT work, but has the functionality I need
# i.e.: dynamically defining content_type's return value using
# the argument from simulate_cgi_upload method.

def simulate_cgi_upload(mime_type = 'image/jpeg')
  class << cgi_file = Tempfile.new('simulate-cgi')
    def content_type() mime_type end
  end
  cgi_file
end
