cucumber supported types

Note: Iterator-style objects (including enumerate and zip) are exhausted during serialization. Reconstruction returns a plain iterator over the remaining values, not the original iterator type.

Note: Objects that turn into Reconnector objects may need to be reconnected after deserialization to fully work. Reconnectors that do not require auth will lazily reconnect on first attribute access; auth-based reconnectors still require an explicit reconnect(...) call (or reconnect_all(...) with credentials).

Note: Due to Python limitations, some types are not supported by Share.

• multiprocessing.* objects (queues, managers, events, shared_memory, connections)
• os.pipe() file handles / pipe-backed io.FileIO
• weakref.ref objects (recreated as weak references; dead refs become placeholders)
• Tokens with authentication (cannot serialize authentication strings)
