Eric Lomore commented on PHOENIX-3355:
--------------------------------------
I actually think 1 is more intuitive, but what I'm possibly missing is how are
we going to alias without if statements (if(name==CEIL)) or an extra map that
maps CEIL, etc. onto its other function(s). To me, both of those solutions are
bulky to maintain, and likely to break in the future. If we do all
instantiations in a Factory, there's a single standard way to instantiate
builtin functions. What do you think, is there another way to do aliasing in
case 1?
