At first I did the same as the author and just dumped the output from `pandoc --bash-completion` et al. into a file, but then I'd have to deal with cache invalidation on every machine that I use. Doing it manually isn't that bad, but remembering to update the file in a bunch of machines is a bit too much ugly for me.

After a surprisingly short Google session, I ended up settling with lazy initialization [1]. Unlike the post I found, I did it all manually, though. Now I just have this tucked at the end of my `.bashrc`:

    function conda {
        unset -f conda

        # shellcheck disable=SC1090
        source <(conda shell.bash hook)
        conda "${@}"
    }

    function _pandoc {
        unset -f _pandoc

        # shellcheck disable=SC1090
        source <(pandoc --bash-completion)
        _pandoc "${@}"
    }

    complete -F _pandoc pandoc
