That may be entirely true and everything you can achieve with Roslyn and T4 templates may be achievable through some more elegant construct in another language.

That may be entirely true and everything you can achieve with Roslyn and T4 templates may be achievable through some more elegant construct in another language. But I've never had the luxury of choosing a tech stack for it's purity of design. So the feature is wonderful in my day to day regardless. I'd love to build 3D experiences in a language like lisp or scheme. It'd be great fun to learn but I don't currently have the luxury of the time it would take to ramp. And I certainly don't have the political capital to convince my entire dev team to change.
