I think there's a fundamental difference between user variables that are used globally (which, indeed, expose the problem you mentioned) and variables that are global by design, like STDOUT and ARGV. Anyway, the next version of Getopt::Long will have the ability to use an arbitrary array instead of ARGV. Now, do you want this to be yet another "if the first argument is an array reference ..." or yet another :config option? -- Johan
