a thought about operations tweaks

one may want to tile and/or partially unroll operation loops
but since such thing characterize operations rather than objects
themselves it is wrong to tag the objects with such info
consider

    matrix<double, tile<3, 3> > tiled1;  //the first one
    //...
    matrix<double, tile<3, 1> > tiled2;  //far from the first one
    //...
    matrix<double> result = tiled1*tiled2;  //what tiling would occure?

instead one can tag an operation itself (when needed)
for exmple one could write like

   matrix<double> result = (m1*m2, tile<3, 3>());

and even
   
   m = (m1*m2, tile<3, 3>())*m3;  //'m1*m2' is tiled; the latter is not

even this primitive form is much more expressive
