type AssociativeProtocol 

type AssociativeProtocol interface {
	Applicable(a types.Any, b types.Any) bool

	// Returns a value obtained by dereferencing field b from
	// object a. If not present return pres == false and possibly
	// a default value in res. If no default is present res must
	// be nil.
