I think it would be better to pickle `typing.List[int]` as `operator.getitem(typing.List, int)`.

    def __reduce__(self):
        if self._special:
            return self._name # __module__ = 'typing'
        index = self._args
        if len(index) == 1:
            index, = index
        return operator.getitem, (self._unparametrized, index)

And there may be a special case for Union. I tried to implement this, but it seems to me that parametrized type doesn't have a reference to unparametrized type, and I don't know this code enough for writing idiomatic code.
