Release Status: release

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

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

   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 
fails.
Interestingly, moving `shopt -s extglob` outside of main fixes the problem.

Fix:

Hey,

We got your report three times. Try to be more patient ;)

This is not a bug. When you use shopt -s extglob, you change how bash parses
the input script. But it has some restrictions:

- You can't enable extglob and use extglob syntax in the same line
- You can't enable extglob in a function and use extglob syntax in the same
line

The recommendation is to do what you did: enable it at the beginning of your
script.

So, not a bug. And don't expect a fix. That's just how it works :-)
