Perhaps it is an option to use the "extglob shell option" of the bash 
shell in the script.
Then you can use a  pattern-list  in the statement. Something like
  [[ ${foo} = @(bar|${foo}|sds) ]]
You have to build the pattern-list in a little bit different way, 
because of the separator "|".

This works in ksh and bash ;-)
I use this on AIX, HP-UX, Solaris, Linux and Cygwin with bash and KSH.
