I'm sure I did.  Is there anything I missed?

```
doc@VM-8-2-debian:~$ env | grep ^PATH
PATH=/home/doc/.yarn/bin:/home/doc/.cargo/bin:/home/doc/bin:/home/doc/.anyenv/envs/pyenv/shims:/home/doc/.anyenv/envs/pyenv/bin:/home/doc/.anyenv/bin:/home/doc/.guix-profile/bin:/home/doc/.guix-profile/sbin:/home/doc/.config/guix/current/bin:/home/doc/.guix-profile/bin:/home/doc/.guix-profile/sbin:/home/doc/.config/guix/current/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
doc@VM-8-2-debian:~$ env | grep GUIX_PROFILE
GUIX_PROFILE=/home/doc/.guix-profile
_GUIX_PROFILE=/home/doc/.config/guix/current
doc@VM-8-2-debian:~$ command -v gcc
/home/doc/.guix-profile/bin/gcc
```

pyenv allows you to set python version for your every project by putting a
`.python-version` file, and you can easily override the version with an
environment variable.  All you need to do is just setting your `PATH`.  I think
it's very useful when you're working with multiple projects.
