> I'd love to see a language where manipulating the language is the core strength, This is the appeal of Julia, where the community uses macros to do things like auto-differentiation (which itself feeds into modeling engines), create domain-specific languages, and to customize compiler behavior (auto-vectorization, target GPU compute shaders).
