1"""Helpers for use with type annotation. 

2 

3Use the empty classes in this module when annotating the types of Pyrsistent 

4objects, instead of using the actual collection class. 

5 

6For example, 

7 

8 from pyrsistent import pvector 

9 from pyrsistent.typing import PVector 

10 

11 myvector: PVector[str] = pvector(['a', 'b', 'c'])
