// Calling cancel with nil sets the cause to Canceled.
//
// Example use:
//
//	ctx, cancel := context.WithCancelCause(parent)
//	cancel(myError)
//	ctx.Err() // returns context.Canceled
//	context.Cause(ctx) // returns myError
func WithCancelCause(parent Context) (ctx Context, cancel CancelCauseFunc) {
	c := withCancel(parent)
	return c, func(cause error) { c.cancel(true, Canceled, cause) }
}

	// then we inline the value expressions into the return argument
	// and then call StaticAssign to handle that copy.
	//
	// This handles simple cases like
	//
	//	var myError = errors.New("mine")
	//
	// where errors.New is
	//
	//	func New(text string) error {
	//		return &errorString{text}
	//	}
	//
	// We could make things more sophisticated but this kind of initializer
