The language specification, while embedded in Python syntax= , is mostly its own language, the Langkit DSL, that is used to specify the = part of Ada syntax and semantics that are of interest to us." I wonder if it would have been possible to create a library of objects dire= ctly in Ada, somehow equivalent in features to Python's Objects, but with t= he advantage of strong typing and a compilation to native instructions. It = would require a major use of interfaces, one for each Python's built-in typ= e class, but it would have been a foundation for many other applications. Vincent
