- * @details
- * - On GCC/Clang, function_name() returns a pretty signature
- *   including namespaces, templates, and parameters.
- * - On MSVC, it also includes return type and calling convention.
- * - This routine removes any leading scope qualifiers (“::…”) and
- *   drops everything from the first '(' onward.
+ * @param loc Source location, defaults to the current function.
+ * @return Function name without namespaces or parameters.
