What is Magnolia?
Magnolia is a generic macro for automatic materialization of typeclasses for datatypes composed from case classes (products) and sealed traits (coproducts). It supports recursively-defined datatypes out-of-the-box and incurs no significant time penalty during compilation. Magnolia provides a simple interface for handling products and coproducts, which is then used by the Magnolia macro to derive typeclasses automatically.
