New submission from Andrew Valencia <ajv-611-065-2...@vsta.org>:
Build with -DLLTRACE, then:
>>> __lltrace__ = 1
>>> a = [1, 2, 3]
0: 100, 0
push 1
3: 100, 1
push 2
6: 100, 2
push 3
9: 103, 3
pop 3
pop 2
pop 1
push [1, 2, 3]
12: 90, 0
pop [1, 2, 3]
15: 100, 3
push None
18: 83
pop None
>>> a[0] = 1
0: 100, 0
push 1
3: 101, 0
push [1, 2, 3]
6: 100, 1
push 0
