I understand that the part beginning with #! and ending with !# are a
block comment in scheme, so they will be ignored by Guile, and that
"Guix wrapper" shows up after a ;, so it will also be considered a
comment by Guile, but I don't understand why the lines following that
need to begin with #\-. I also don't understand why Guile doesn't
complain about it. Why do the lines begin with #\-?
