# These functions are referenced from the pickle archives produced by
# ScriptModule.save()


# These (`build_*`) functions used to be used by `pickler.cpp` to specify
# the type of the list for certain special types, but now all lists get
# a type attached and restored via `restore_type_tag` below. The legacy
# functions should stick around for backwards-compatibility.
