Unassigning. I don't think that r82043 is the real culprit here; that bugfix just happened to expose a deficiency in the peepholer; one that's already present in other situations: >>> dis.dis(lambda: 2(34)) 1 0 LOAD_CONST 1 (2) 3 LOAD_CONST 4 (12) 6 BINARY_MULTIPLY 7 RETURN_VALUE >>> dis.dis(lambda: (23)4) 1 0 LOAD_CONST 5 (24) 3 RETURN_VALUE Antoine, does your patch take care of this case too?

Unassigning.  I don't think that r82043 is the *real* culprit here;  that bugfix just happened to expose a deficiency in the peepholer;  one that's already present in other situations:

>>> dis.dis(lambda: 2*(3*4))
  1           0 LOAD_CONST               1 (2)
              3 LOAD_CONST               4 (12)
              6 BINARY_MULTIPLY     
              7 RETURN_VALUE        
>>> dis.dis(lambda: (2*3)*4)
  1           0 LOAD_CONST               5 (24)
              3 RETURN_VALUE        

Antoine, does your patch take care of this case too?
