I use pyenv [1] on Ubuntu 20.04.3 LTS, which needs the following configuration in ~/.bashrc:

```
eval "$(pyenv init -)"
```

The `pyenv init -` called above will be expanded into the following when evaluated:

```
$ pyenv init -
export PYENV_SHELL=bash
source '/home/werner/Public/repo/github.com/pyenv/pyenv.git/libexec/../completions/pyenv.bash'
command pyenv rehash 2>/dev/null
pyenv() {
local command
command="${1:-}"
if [ "$#" -gt 0 ]; then
shift
fi

case "$command" in
activate|deactivate|rehash|shell)
eval "$(pyenv "sh-$command" "$@")"
;;
*)
command pyenv "$command" "$@"
;;
esac
} ```

Now, I want to eval of slightly revised version of the above `pyenv init -`, which means that I must eval these complicated commands directly. I tried with the following method:

```
eval "$(
# Here comes the revised version of the above `pyenv init -`
....
)"
```

But it seems this method doesn't work, especially, the following line in the original version of `pyenv init -`, which adds the bash completion for pyenv doesn't work in my revised one:

source '/home/werner/Public/repo/github.com/pyenv/pyenv.git/libexec/../completions/pyenv.bash'

Any hints to make a completely equivalently eval with these complicated commands directly?
