+Compile-time error thrown when trying to bind to a natively typed variable.
+
+Since native variables explicitly don't have the concept of a container at
+run time. Thus it does not make sense to support both binding and assignment,
+and Perl 6 supports only assignment (which makes more sense, because native
+types are value types). So use assignment for natively typed variables.
