Go supports custom domains for package names.
2022-08-21 I tried to Mycomarkup from older
github.com/bouncepaw/mycomarkup import path to a new
lesarbr.es/mycomarkup path (the repo is actually on SourceHut). It took a lot of time, pain, and confusion. The docs are not really understandable (which is pretty uncommon for Go).
In the end, it didn't really work for 100 %, so I instead moved to
git.sr.ht/~bouncepaw/mycomarkup. They made it work.
