Thanks for pointing this out. I think we should support user specified 
vector size for the generic vector type. 
But I'm not quite sure about the syntax here. In C/C++ it is possible to 
calculate number of units by vector_size/sizeof(scalar_type), in Fortran 
we have to use Integer to represent char, short, int and long. Where could 
I specify kind of scalar type? Somthing like vector(Integer(1), 16)? 

Thanks,
Sa
