Project mention: The Performance Impact of C++'s `final` Keyword | news.ycombinator.com | 2024-04-22.NET is a little smarter about switch code generation these days: https://github.com/dotnet/roslyn/pull/66081
Yea, that's true. I forgot about that. I did think of Clojure CLR, but I don't get the impression that this is an all that natural or used implementation. ClojureScript is obviously much more used, although it is still a "different" language.

Project mention: .NET Compiler Platform ("Roslyn") Analyzers VS Metalama - a user suggested alternative | libhunt.com/r/roslyn-analyzers | 2023-12-07Metalama allows you to create your own code validation rules without the complexity of Roslyn. It is especially useful to validate source code against architecture or design patterns.
Project mention: Classes vs. Structs in .NET. How not to teach about performance | news.ycombinator.com | 2023-11-04How is that relevant to the vast majority of the code targeted by LINQ?
The niche scenario you have outlined is partially covered by a recent System.Numerics.Tensors package update (even though I believe it would have been best if there was a community-maintained package with comparable quality that can be decoupled from .NET release cycle and trade-off support/compat guarantees in favour of more aggressive improvements in the future).
The goal of LINQ itself is to offer optimal codepaths when it can within the constraints of the current design (naturally, you could improve it significantly if not for backwards compatibility with the previous 15 or so years of .NET codebases). The argument that it's not good because it's not the tool to do BLAS is just nonsensical.
There is, however, an IL optimizer that can further vectorize certain common patterns and rewrite LINQ calls into open-coded loops: https://github.com/dubiousconst282/DistIL
