Forgot to mention, a while back I proposed an extension to 
stringlist_to_regexp where using -re as an escape means don't use 
string_to_regexp because this part is already a regexp.

Using that method, we'd get:
...
set re \
     [stringlist_to_regexp \
         -re $hex -re {\s+} "<" -re "(" "." -re ")?" "foo"]
...

Thanks,
