----------------
I'd expect to have to do this recursively for each `IMPORT` in the PCH, since AST files list only direct imports.

However, the AST file for PCH I use in tests contains imports of `ModCommon1`, `ModCommon2`, `ModPCH` even though only `ModCommon1` and `ModPCH` are imported directly in the header.
