Subject: OptionParser order of arguments

all-

i've had a lot of success working with OptionParser, but there is one  
burr in the saddle- order of arguments parsed.  sample code:

require 'optparse'
class MyClass
   def initialize(arguments)
     @options = {}
     opts = OptionParser.new
     opts.on('--some-param [PARAM]') {|param| @options[:param] = param}
     opts.on('--print-param') { puts @options[:param]}
     opts.parse!
   end
end
MyClass.new(ARGV)

put that in a file (opt_test.rb) and run the following:

ruby opt_test.rb  --print-param --some-param tom
$ nil
ruby opt_test.rb  --some-param tom --print-param
$ tom

obviously, it works as intended, but it does require that one pass  
arguments in a particular order.  anyone know of a way around this?

thanks all,
tom
