-// Cause recursively unwraps an error chain and returns the underlying cause of
-// the error, if possible. An error value has a cause if it implements the
-// following interface:
-//
-//     type causer interface {
-//            Cause() error
-//     }
-//
-// If the error does not implement Cause, the original error will
-// be returned. If the error is nil, nil will be returned without further
-// investigation.
