Problem: - `typedef` is a keyword which comes from C and carries with it old syntax that is hard to read. - Creating type aliases with the `using` keyword allows for easier future maintenance because it supports template syntax. - There is inconsistent use of `typedef` vs `using`. Solution: - Use `clang-tidy`'s checker called `modernize-use-using` to update the syntax to use the newer syntax. - Remove unused functions to make `clang-tidy` happy. - This results in consistency within the codebase.
