Missing this is causing turbojson to be unusable with Python 2.7, and
FTBFS when it is default (as on Ubuntu):

| ...
|   File "/usr/lib/pymodules/python2.7/peak/util/assembler.py", line 221, in TryExcept
|     next_test.JUMP_IF_FALSE, Code.POP_TOP,      # remove condition
| AttributeError: 'Label' object has no attribute 'JUMP_IF_FALSE'
