ioeric added a comment.
Thanks for the comments! I addressed comments in the symbol collect part (I
think?). Will add tests in a followup patch.

`mutable` was here because of `llvm::Regex`. Matching again `a llvm::Regex` is
not a constant operation, but we would still like the lookup function to be
`const`.
================
Comment at: clangd/index/Index.h:155
llvm::StringRef CompletionDetail;
+ /// A URI for the header to be #include'd for this symbol, or a header like
+ /// "<...>" for system headers that are not repository independent (e.g.
STL

In our latest offline discussion, we concluded that this would be either URI of
a file (in .inc case) or a literal string that is suitable to be inserted. I
left resolving IWYU targets as a `FIXME` in this patch as it is more work and
doesn't seem to cause any trouble at this point. Will revisit when it actually
becomes a problem.

I think it'd be easier to justify the behavior with a white list. There are
other symbols like `NamespaceAlias` etc, which we might or might not be
collecting.
