In HAL we deal a lot with properties and expose both something a'la

 ANY GetProperty(..)
 STRING GetPropertyString(..)
 INT32 GetPropertyInt32(..)

so e.g. in like Python you'd use the GetProperty method whereas in
strongly typed languages you'd use the method with the typename after
it. If the user tries GetPropertyString("UID") an exception is thrown
because of type mismatch.
