  bash-5.3-alpha$ uname=1
  bash-5.3-alpha$ echo $(( uname - $(echo 1) ))
  0
  bash-5.3-alpha$ echo $(( uname - $(case x in x) echo 1;exit;;esac;echo 0) ))
  uname: extra operand '-'
  Try 'uname --help' for more information.

Which could be avoided by using double quotes:

  bash-5.3-alpha$ echo $(( uname - "$(case x in x) echo 1;exit;;esac;echo 0)" ))
  0
