Hi Joel ,

thanks for your reply.

But i doubt that BOOST_PROTO_AUTO could solve this problem, because it 
copies all values no matter for arrays. Since this can cause a large 
amount of data to copy this would definitely slow down for example 
matrix-vector multiplication.

What i want is that deep_copy should copy only single values like 
double, float or int and not arrays.

B/Rgds
Kim
