VIM ver. 8.2 (not self compile, .deb package from debian repo) OS: Debian BullsEye Reproduce the problem: 1. Install by native package manager `git clone https://github.com/elixir-editors/vim-elixir.git ~/.vim/pack/lang-support/start/vim-elixir` 2. Remove all lines in `~.vim/vimrc` and keep just lines mentioned in README https://github.com/elixir-editors/vim-elixir#configuration 3. Remove all plugins and keep just vim-elixir 4. Syntax highlighting does not work
