Extended Description

I was just looking at bug725.sac, an incarnation of Conway's Game of Life,
It does this, in function addpad():
  sh1 = shape(a);
  pad1 = [genarray([sh1[1]],0)];
  add1 = pad1 ++ a ++ pad1;
The ++ functions are unable to AWLF, because of the way that pad1 
is defined. 
If the code is rewritten this way:
  sh1 = shape(a);
  shpad = [ 1, sh1[1]];
  pad1 = genarray(shpad,0);
  add1 = pad1 ++ a ++ pad1;
then the whole shebang wolds into a single WL. I think I'll go
change blife.sac to work this way. However, it would not
be a lot of work for some keener to make AWLF work on the original
blife.sac code.
