Part of the specific case means it's Python 2.4 or later. In 2.3 it
looks like this:
2 0 LOAD_GLOBAL 0 (x)
3 LOAD_CONST 1 ('abc')
6 LOAD_CONST 2 ('def')
9 LOAD_CONST 3 ('xyz')
12 BUILD_TUPLE 3
15 COMPARE_OP 6 (in)
18 JUMP_IF_FALSE 11 (to 32)
21 POP_TOP
so in this case (Python 2.3), the answer is no.
