I don't know D (I have prejudices against la= nguages that use curly brackets). In what areas is ahead Ada and in what ke= y areas is crippled? D is lacking - #1 no way to switch braces to begin and end :), the ability = to create new ranged types no via OO. It does have a concept of types above= C and C++ but no where near Ada's. As an extension of that it can only cre= ate 0 indexed arrays, but you can use enumerations, so some support. There = are other issues but mostly revolve around lacks in terms of defining types= and as a direct result compile time checks related to those lacks. It's wa= y ahead of C/C++, Java, etc. and there are ways to create types in OO but t= hen all checks become dynamic. D is ahead - 3 true open source (no virused runtimes) implementations (dmd,= lcd2, gdc), phobos (D's runtime) is incredibly rich, functional, parallel = computing, concurrency, etc. Ada's annexes are primitive in comparison. Eas= ier interfacing with C. Community support, resources, etc. etc. dub - packa= ge management and build system, etc. built in unit testing, better syntax f= or pre and post conditions, and tons more. A few tweaks to D's type system and not sure Ada would have anything all th= at unique or beneficial at all. > Well, Nim is still immature and a little buggy. By the way, Rust author h= as abandoned Rust and turned into Nim. An . Goes to show you both languages no more than a fad. The author of Rust went to nim because of C output since he is working on a= n OS. BTW, D has already successfully been used for creating OSes, etc. > Well, Nim is not a Python like language at all. Oh my, it was created to be a compilable Python from the start..... David Botton
