              Status:  new      |   Priority:  not urgent at all
           Milestone:  5.4      |  Component:  core libraries
             Version:  5.2.0    |   Keywords:  performance, numeric tower
Estimated difficulty:  easy     |

 Just a note to myself so I don't forget:

 Get rid of the nested ifs in number dispatch by combining the headers of
 objects and then dispatching on the result using `switch`.

 The mechanics would be a little bit ugly but possibly it's faster. Even if
 it isn't faster, it might be more readable.

 Something like:

 {{{
 switch(COMBINE_TYPES(a, b)) {
 case FIXNUM_FIXNUM:
    blabla
    break;
 case FIXNUM_FLONUM:
    blabla
    break;
 ....
 }
 }}}
