Outside of Python, binary operators are (in the examples I can think of) 
more often more strongly associated with the second argument than the 
first, even to the point of switching the order of 2nd arg and operator.

English: Start with A, add B, subtract C, and assign the result to D.

   load A
   add B
   sub C
   stor D

Calculator tape (with literals, not symbols)
   B +
   C -
   D =

I suggest relinquishing the rule, except maybe to suggest consistency 
within an expression, if not the whole file.
