#For Jython, removed co_names, co_consts since these are implementation details
|
|
# that may never get implemented, and removed flags since there are implementation
|
|
# differences that may never line up. Still failing on one test for varnames
|
|
# because I think it is possible that the order of varnames might be useful (in
|
|
# order declared) and Jython doesn't quite get that right.
