a little gem lurking in the magnolia docs: "however, there is the flexibility to provide additional type parameters or additional implicit parameters to the definition". Adding additional implicits lets you use other typeclasses in the derivation. @propensive

In my use case I would have to have def combine[T](caseClass: CaseClass[InputTC, T]): OutputTC[T] so CaseClass captures instances of one TC and produces an instance of other TC. Maybe this works right now, will have to check.
That's a bit more complicated, but it might work, with some effort. Derivation can take place in a type-dependent context. It's not exactly the same, but have a look at this example: https://github.com/propensive/magnolia/blob/master/examples/shared/src/main/scala/show.scala …

You inspired me to create this: https://gist.github.com/Krever/271282ae0cddaed019fc6eec99cc7455 … so it can be done! ... but 1) its to complicated imho 2) I had to cast ;/

I'd like to spend longer looking into this... and try to remove those casts. :)
