He brought me much joy in tinkering, first with Pascal, then with Oberon.

In looking up and then reading that article, I discovered that not only has Oberon been actively maintained, but that there is a successor, A2. Now that I’m back to being a hobbyist, I look forward to more joyful tinkering courtesy of his great mind.

Edit: in the course of further investigation, I found many dead links. But I also found this A2 repository that shows activity from as recently as 2 months ago.
