Ada is a lot of fun and a great thing which is ruined (and blessed) by the fact there's de facto only one implementation and company behind it out in the open, and that is semi-closed / license PITA. There were improvements over the years by AdaCore, but I think this altogether hurt the adoption of such a great language in general - no other wide open implementation (like Rust has). If you want to see an extreme example of such a hurt, take a look at Allegro CL and Franz; Imagine having that out in the open and what it'd do for CL, but at least CL has great alternatives in the open like SBCL, whereas Ada doesn't.
