Anders is a really good language designer. Everything this dude touches turns to gold. He was also behind C# and as far as enterprise languages go C# is a joy to work with. TypeScript is the same way. It's all really well thought out and instead of getting in the way the type system actually helps because you can leverage the dynamic aspects of JavaScript during the prototyping phase and then gradually add types as the design is fleshed out. Typed Racket I think is the other language that gives you similar capabilities but I haven't played enough with that one to have an opinion yet.
I assume you mean Delphi. Other than being now a little bit old school (not surprising for language with roots in Pascal), Delphi was and is an excellent language. Delphi was composed of a language (an ObjectPascal) along with the IDE, application framework, and Visual Component Library (VCL). These conceptual parts were all further developed in C#/Visual Studio, but they were already damn good in Delphi over 20 years ago, ahead of their time.
