Agreed. As a matter of fact the simplest convolutions of tensors 
are out of date. It is like there's no need to calculate inverse 
matrix. Mir is the usefull work for author, of course, and 
practically almost not used. Every one who needs something fast 
in his own tasks should make same things again in D.
