/**
* A derived path with hints in the form of optional concrete output paths in the built case.
*
* This type is currently just used by the CLI. The paths are filled in
* during evaluation for derivations that know what paths they will
* produce in advanced, i.e. input-addressed or fixed-output content
* addressed derivations.
*
* That isn't very good, because it puts floating content-addressed
* derivations "at a disadvantage". It would be better to never rely on
* the output path of unbuilt derivations, and exclusively use the
* realizations types to work with built derivations' concrete output
* paths.
* A built path. Similar to a `DerivedPath`, but enriched with the corresponding
* output path(s).
