If we have this we have still the problem that moving a big 
struct is slow.
My 'make' is a lot faster. Therefore I suggested this new 
behaviour instead of the old deliberations about 'auto ref'. And 
I thought, because it is probable, that 'auto ref' will never 
work for non-template function, my Idea would be a nice 
alternative. :)
