i apologize this issue I am already aware of. It was the reason I didn't want to change the type to begin with and also why I was trying to  sema template deduction https://discourse.llvm.org/t/rfc-represent-hlsl-matrix-layout-in-the-clang-ast/91469

As Chris pointed out that wouldn't be enough so at least for this part I am still actively considering how to address Chris's feedback.
