this is how to build dsls that don't fuck the global namespace



	# the entire concept of building a dsl means defining domain terms on an
	# object, it's so much simpler to start with the dsl itself being a blank
	# slate that simply relays certain methods to a scope
	#
	class DSL
	instance_methods.each do \|m\|
	undef_method m unless m[%r/\A__\|\Aobject_id\Z/]
