How long have you used it and how is it?

I’m pretty curious about those kinds of distros, and don’t really like how nixos is completely hosted on github (and all the drama that constantly comes from the community, and the bad documentation for many things, …).

However, guix seems such a niche project that I feel like it can’t really be used.

You should put some quotes where you use the array:

not_what_you_think=( "a b" "c" "d" )
for sneaky in "${not_what_you_think[@]}"; do
  echo "This is sneaky: ${sneaky}"
done

This is sneaky: a b
This is sneaky: c
This is sneaky: d
