I think this would make an interesting proposal, especially since people often want to add new #pragmas to Clang and introduce them into the AST.

OpenMP would be a good test of advanced Clang pragma handling. If you're going to propose OpenMP, be sure to specify the intended limitations---e.g., you might want to tackle semantic analysis and AST representation but not actually try to generate IR for any particular OpenMP runtime.

I, personally, am not terribly interested in this project.
