I agree.  But it is a good idea to look briefly at Clang architecture
and copy it as much as makes sense for your project.  You can even
take whole classes like SourceManager/SourceLocation or diagnostics
infrastructure (after decoupling from preprocessor since you don't
have one), or use LLVM's ADT library.
