Nathan Bubna updated VELOCITY-510:
----------------------------------

    Fix Version/s: 2.0
       Issue Type: Wish  (was: Improvement)

There's no way we would ever have overloading by type, as VTL is nearly 
typeless.

Overloading by number of arguments may take some pretty drastic changes.  I 
don't see this happening in a 1.x timeline.

> It would be very useful to be able to overload macro definitions with 
> different number of/types of parameters.
> Many, many times there is aneed to slightly tweak an existing macro to give 
> it new capabilities.  Rather than create a new one with a different name, it 
> would make it much neater if you could create a new one with the same name.
> Another way to achieve similar results would be to allow a variable number of 
> parameters.  Although not quite as formal, this would provide a reasonable 
> alternative.
