The syntax of closures (they had to invent their own name, anonymous methods) is very long-winded. And generics? Only useable after several versions. Which leads to the most important point: quality is s*it (I'd suppose because they cannot tame the complexity any more).
Hello 'it works' likely won't get you far :-)
It's a pity, but the sooner they bankrupt the better. Something more focussed and contemporary might emerge or people invest and switch to FreePascal. Would love to have a native Pascal based ecosystem which would be innovative and friendly, like let's say, Xamarin!
