Implicit wrappers for non-typedpy types

[loyada]

Suppose I defined a class Point, which is non-Typedpy class.

I want to be able to do the following:

class Example(Structure):
      point = Field[Point]
      point_by_name = Map[String, Point]
      any = AnyOf[Integer, Point]

and I want serialization to be on a best-effort basis in such cases.
and I want pickling to raise an appropriate error message whenever the class has implicit class wrappers.
