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.
