Not so fast. Here's what I get (python2.6.4, 64 bit):
$ python -mtimeit -s "class A(object): __slots__ = ('a', 'b', 'c')" -s
"inst = A()" "inst.a=5; inst.b=6; inst.c=7"
1000000 loops, best of 3: 0.324 usec per loop
$ python -mtimeit -s "class A(object): pass" -s "inst = A()" "inst.a=5;
inst.b=6; inst.c=7"
1000000 loops, best of 3: 0.393 usec per loop
Now what?
