If there are many searches in the `$LOAD_PATH` in the user environment, require will perform unnecessary searches that are not needed. In contrast, `require_relative` is efficient because it uses a relative path. Racc requires Ruby 2.5+, it is possible to use `require_relative`, which was introduced in Ruby 1.9. https://github.com/ruby/racc/blob/v1.8.0/racc.gemspec#L44
