[Dune] ALU* #define

[Oleh Krehel]

Dear DUNE developers,

I've come across this code snippet:

./dune-grid/dune/grid/alugrid/2d/alu2dinclude.hh:32:#define ALU2DSPACE
ALU2DSPACENAME ::
./dune-grid/dune/grid/alugrid/2d/alu2dinclude.hh:35:#define
ALU2DSPACENAME ALU2DGrid

Is there a reason it can't be replaced with

namespace ALU2DSPACE = ALU2DGrid; ?

This way constructions like

switch( elementType )
    {
      case ALU2DSPACE triangle:
        //...
        break;
      case ALU2DSPACE quadrilateral:

would be made more legible.

best regards,
