in particular, for switch cases which declare const, use a new block

 # To do
 
+- [ ] Settle on a C standard (C11?), and use safer string handling functions provided by it.
+  - See make lint for purported insecurities
 - [ ] Document creating new applications, e.g., as in [Asana for Linux](https://git.nunosempere.com/NunoSempere/asana-for-linux)
   - [ ] This time, use something other than Whatsapp as an example syslink.
 - [ ] Fix bug about distorted audio. Maybe related to [this pipewire issue](<https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1547>)?
