Bash Version: 4.3
Patch Level: 11
Release Status: release

  Not sure if this is a bug (it does bug me a little), however:

    shopt -s extglob
    local line='     x bar'
    echo "${line##*( )}"
    case "$line" in
      *( )x*) ;;
      *) ;;

   fails with a syntax error on the first parenthesis in the case statement. It 
does turn extglob on
  in other contexts (the echo line), but the extglob in the case statement 
Interestingly, moving `shopt -s extglob` outside of main fixes the problem.

        [Description of how to fix the problem.  If you don't know a
        fix for the problem, don't include this section.]
