C# metaprogramming is called T4 templates, Roslyn plug-ins, 
compiler attributes, reflection and code generators.

Are they clunkier than D?

Surely, however C# comes with Unity (what happened to Remedy?), 
Orleans, CUDA (including GPGPU debugging), IoT (Meadows), Cloud 
SDKs for GCP/AWS/Azure, Blazor, Uno, MAUI,....

D, well it has MIR and vibe.d, that is about it.
