  While I agree with that (yes, I'm not a fan of OOP myself) I do find the
':' notation worthwile as a form of scope for functions (mostly with
userdata).  I find:

	config = tls.config()
	config:protocols("all")
	config:verify_client(true)
	config:ca_file("trust_these")
	config:cert_file("my_cert")

	server = tls.server()
	server:configure(config)

	connection = server:accept_socket(s)

nicer than:

	config = tls.config()
	tls.config_protocols(config,"all")
	tls.config_verify_client(config,true)
	tls.config_ca_file(config,"trust_these")
	tls.config_cert_file(config,"my_cert")

	server = tls.server()
	tls.configure(server,config)

	connection = tls.accept_socket(server)

  As it stands, my top level tls module [1] only has five functions instead
of some 80 functions---the configuration functions are only available to the
config "object" (for lack of a better term); the context functions are only
available to the "context" (or in this case, "server") object.  It's a form
of organization.
