Another good thing about the operator-and-assignment is that it can
save writing and make parsing faster.
  For example, consider this:

#declare Table[Index1*2+Offset1][Index2*2+Offset2] =
Table[Index1*2+Offset1][Index2*2+Offset2] + 1;

vs:

#declare Table[Index1*2+Offset1][Index2*2+Offset2] += 1;
