I think this is only, because this way we address the map faster.
With "|", "&", "<<" and ">>" we can quickly transform (x,y)
coordinates to the memory
address and back.
Nuage mentioned that accessing memory is by far more time consuming
than computing
the address.  So probably "+", "%", "/", "*" are fast enough, and
arbitrary rectangle maps
possible.
