I would say that the only really up to date ports are SBCL and Scheme
though Go was updated to S standard some years ago. Many of the ports
are stuck in pre-S configuration. It was sort of inevitable, that in an OS project
manned by volunteers, that a language like Shen, spread uniquely across
many platforms, would end up with obsolescent unmaintained ports. As
I said in
my essay (Forks and Abandonware section), this is a problem with
OS projects.
BUT there is a big but - it might not matter. You see Yggdrasil is designed
to operate with all platforms but only needs one to run. Confusing? Read
Today I'm picking up coding Yggdrasil in a stripped down type secure version.
This is the first code I've written in a time.
So if
Yggdrasil works as planned, the work doen on these ports will not be wasted.
