New submission from Daniel Colascione <[EMAIL PROTECTED]>:
Consider:
import dis
def foo():
if 0 and 1: return "hi"
dis.dis(foo)
What I get is
2 0 LOAD_CONST 1 (0)
3 JUMP_IF_FALSE 15 (to 21)
6 POP_TOP
7 LOAD_CONST 2 (1)
10 JUMP_IF_FALSE 8 (to 21)
13 POP_TOP
14 LOAD_CONST 3 ('hi')
17 RETURN_VALUE
18 JUMP_FORWARD 1 (to 22)
>> 21 POP_TOP
>> 22 LOAD_CONST 0 (None)
25 RETURN_VALUE
What I'd expect to see is:
1 0 LOAD_CONST 0 (None)
3 RETURN_VALUE
