A couple gotchas when useing new.code():

1. co_names, co_varnames, co_freevars, and co_cellvars take tuples of
strings; passing unicode strings crashes the interpreter. co_consts,
however, is unicode-safe.

2. Some co_flags should be checked to be consistent with other args; for
example, shouldn't CO_NOFREE be set if co_freevars is empty?
