Hi,
syntax like

#local size = big ? 100 : 50;

(from C "operator?" ) isnt working, and writting it normaly as:

#if (big) #local size=100; #else #local size=50; #end

is quite long (I like to keep my syntax short). So I wanted to write a tiny 
IfElse function, like:

#macro IfElse(A,B,C) #if (A) 55 #else 30 #end #end

#local DD = IfElse(variant_Wide, 50, 100);

but it gaves a pares error.

I replaced it with good sytnax:
  #macro IfElse(A,B,C) select(A-1,C,B,C) #end
that do work, but just for curiosity, how to make previous syntax work 
also?
