LG with a comment.



================
Comment at: clang-tools-extra/clang-tidy/readability/NamespaceCommentCheck.cpp:110-111
+      Lexer::getSourceText(TextRange, Sources, getLangOpts())
+          .rtrim('{') // Drop the { itself.
+          .rtrim();   // Drop any whitespace before it.
   bool IsNested = NestedNamespaceName.contains(':');
----------------
This all seems rather hacky. I believe, this will fail miserably when there are comments before the `{`. Can you leave a FIXME to rewrite this logic in terms of tokens instead?
