   OK, so it's not a bug, but I see a handy feature to be
   added later here.
   If I have a function:

   foo() 
   {
	   if [ -d $whatever ]
	   then
		   cd $whatever
	   else
		   exit
   }

   This will exit from the shell, not the function only. How can
   I exit from just the function.

Use "return".
