I like davido's suggestion of a %^C hash with the command line parameters that are used to invoke perl. This allows the programmer to use the value of F (or anything else defined on the commandline) for a join IF he/she knows that it is safe to do so - i.e. if it is not a pattern but a simple string, see duff's post in this thread.
