I'm sure up to a certain extent 😄 But I haven't tested it. IIRC sometimes one can help the compiler by defining such checks recursively. And if the checks only...
Are you sure that these are caused by AbstractDifferentiation? Was the AbstractDifferentiation update the only change compared with e.g. runs on the master branch? I wonder because, e.g., the latest...
Did you actually check type stability? Or is it just a general comment that there could be issues?
Did you try the master branch? Hopefully the recent simplifications already improved things.
> Tangent{Struct}(;x=NoTangent(), y=one(T)) Did you try `Tangent{typeof(mystruct)}(; y=randn(T))` or similar as well (ie without specifying `x`)?

@ranocha the action seems to error, do you know what's the problem?
