// AbsMoveable is an interface implemented by address types that can be either
// the source or destination of a "moved" statement in configuration, along
// with any other similar cross-module state refactoring statements we might
// allow.
//
// Note that AbsMovable represents an absolute address relative to the root
// of the configuration, which is different than the direct representation
// of these in configuration where the author gives an address relative to
// the current module where the address is defined. The type MoveEndpoint

_ AbsMoveable = AbsResourceInstance{}
_ AbsMoveable = ModuleInstance(nil)

// ConfigMoveable is similar to AbsMoveable but represents a static object in
// the configuration, rather than an instance of that object created by
// module expansion.
