Hi there, 
if that testcase is "invalid", then that means that the mapper statement does
not work with template classes at all

It would mean that for a struct with a template datatype

template <typename T>
struct myvec
{
size_t len;
T *data;
};


and must first write something like

typedef  std::myvec<double> doublevec;


before one can use the mapper then on doublevec.


But that makes the mapper rather useless for usage with templates as one has to
define a specific mapper for each template usage...
