Do you have a suggestion on how to modify these lines?

I think that is actually a bug in Diffractor introduced by this change, unintentionally.
We should isolate and fix it, and add a test of our own for the at case.

The API remains the same, that code should still work and it looks like it does (until it hits this bug in map)

Sounds good! I think DifferentiationInterface might have accidentally become PkgEval for AD ^^

Actually the problem is already in v0.2.7, but not in v0.2.6
