1773	Idea: numeric dispatch with switch	sjamaan		"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;
....
}
}}}"	defect	closed	not urgent at all	5.4	core libraries	5.2.0	wontfix	performance, numeric tower		easy
