Given a class `SomeClass` that has a field of an interface type(or superclass) `A` and given two instances of `SomeClass`, one having `B extends A` in that field, another having...

Hi, this PR is more of an exploratory PR, to see whether this idea is useful for the general public. Internally at our company we're using nixops to deploy to...

Control over ThreadLocal swapping
