I would like to do beginx(); or beginy(); or beginz(); or beginc(); in gmic. The reason why I would like to see these is that one can make variables only once for x or y and thereby avoiding speed issues. Are these possible now?
This is equilavent to:
for(x=0,x<w,x++, foo=x; for(y=0,y<h,y++, foo*y; ); );
Additional idea, I would like to do iv#channel or iv#perchannel inside fill.
