To be fair, I don't think this is as significant as it sounds. I agree,
__simd had no real design, it was just a convenient implementation for DMD,
but isn't that always the case for compiler intrinsics? In most cases, LLVM
tries to mirror GCC intrinsics, but there are many significant distinctions
between LLVM and GCC's intrinsics, making versions in the code for each
compiler there too.
In my experience, there is always versioning issues when making use of
compiler intrinsics, what's important is that the language is able to wrap
them up cleanly and effectively. D currently satisfies this requirement to
some extent, but in my experience with std.simd, to get to the 100% mark, I
really need __forceinline. I can't really finish std.simd to a satisfactory
level without it.
