Motivation
This doesn't build because lots of conversions are needed. In code that is already Unix-only that is especially annoying.
I wish there was a way to have a namespace-specific implicit coercion, so I could have
Descriptor <-> int
implicit coercsions innamespace nix::unix
but notnamespace nix
