Research direction

Start with boost::log::format_named_scope and reproduce the shown anonymous-namespace example using the reported format string. Inspect the formatter's handling of qualified function names; done means the output preserves the full name, including the anonymous namespace, rather than truncating it to anonymous}::test.
