GetoptLong is hard coded to act directly on ARGV. That limits it's usefulness or requires the poor practice of setting
ARGV in code. It's probably not a good idea to directly manipulate ARGV anyway. It's better to always have a fall back
copy, so maybe ARGV should actually be frozen. In any case a quick solution is to add something like the following to
GetoptLong:

  def argslist
    @argslist ||= ARGV.dup
  end

  def argslist=(args)
    @argslist = args
  end

And then subing /ARGV/argslist/g.
