commenting after seeing multiple comments here, after about a day.

first of all, thanks, guys, to all who replied. that's a wealth of info to follow up on.

referring to the comments seen so far:

I considered mentioning (Free) Pascal, but thought of not doing it, because I thought it is nowadays too niche, even though it is one of my early programming language loves (forgetting that the title of my post says "less popular languages" :)

and I also didn't think of Ada at all, somehow, although have been interested in it, too, lately, and have been checking out websites and blogs about it, and also have been searching hn.algolia.com for posts about it.

so it was cool to see multiple mentions of Ada here, by people who like and use it.
