Is it safe to override `__init__` for a `PClass`?

[travis-leith]

Currently, PClass exposed constructors of the form MyClass(**kwargs: Any).
If I want to support static type checking, I need a factory method. But if I want to prevent people from using the standard constructor, I need to overrde __init__. Is this a safe thing to do or might it break something?

If pyrsistent were to be rewritten based on dataclasses, would this be a non issue?
