@vchuravy this variant of the issue is not resolved by your PR.

I think the ChainRules and proposed `EnzymeRules` interface solve two orthogonal problems. The need for the design proposed here is making an interface for Enzyme to take any Julia custom...

Per an earlier offline discussion. Active vs const is easy since a const rule can always fallback to active and not use the derivative result. Active and duplicated are incompatible...

You should be passing Active(2.0) d/dx x^2 = 2x = 4 (evaluated at 2)
