    When someone defines a C-style enum with `typdef enum {...} name`, the entirety of the enum (from typedef to name) is highlighted by `modernize-use-using`. This can be a bit jarring in longer enums where there can be hundreds of lines of enum entries marked with a warning. It also doesn't seem to be in line with the rest of the `modernize-` lints; in `modernize-avoid-c-arrays`, `int arr[3]` would only highlight the `int` and not everything through the `[3]`, and `modernize-loop-convert` similarly only highlights the `for`. 

This issue is made worse in the VS Code clangd extension, where `modernize-` lints are marked as deprecated, and are struck-through in addition to being highlighted--greatly reducing readability of the enum entries. For example
