I think that is probably the best way in C++ (in dot-m Bill is probably 
right).. You could also use Bill's solution in C++ using class_name() 
instead of type_id() and replace the two integer compares above with a 
single string compare to "uint8". However I think two integer compare 
will be faster than a string compare...
