Yes, I have seen that. Of course the JITer will not perform the same level of optimizations as the fullblown code generator, but then you can just call that if you like. The new JIT engine does support SIMD [1]. And C# can generate SIMD code using various libraries (I think MS has one, and I know Mono does). And various people have shown how to do fullblown x86 assembly code generation and execution from within C#, but it's fragile.
