Very similar problem. We have a two-part problem where we both have enough of them that parsing a header would be too slow _and_ the HLSL language actually can't represent them. The later we're working to fix. My hope is that eventually we can write the HLSL libraries in HLSL and use a pre-compilation step (PCH or Module-style) to get past the performance issues.
