As far as I can tell, a few years ago I designed a macro which takes four 
variables as inputs, and got it to do what I wanted by calling it with (a 
mistake?) only three.

If this were allowed, is there a rule as to how pov will re-interpret the 
variables with something like variable promotion:   a,b,c gets taken as 
a,b,c,c?
