Object pascal has a level of rigor that made building apps that were performant and fully capable. Lots of execution speed but it was a lot harder to do the pitfalls of c/c++ and not tied up in some arcane thing like powerbuilder.
It's really a shame that Unix ate the world. I've never had a chance to use Pascal in a professional context (other than reading old code) because C/C++ had taken over for OS development by that point.
Above all it made programming fun.
