Content
The opcode module contains several collections: `cmp_op` `hasconst` `hasname` `hasjrel` ... which are only used for `in` checks. At the same time, they are stored as `list`s and `cmp_op` as tuple. Both these types are not optimal for `__contains__` checks. Maybe it is worth at least to convert them to `frozenset` type after they are filled?
