OptionParser::InvalidOption has an accessor "args".
You'll be possilbe to:

    other_options = []
    begin
      opts.parse!
    rescue OptionParser::InvalidOption => e
      other_options.concat e.args
    end

    # ... and
    orb = CORBA::ORB_init($0, other_options + ARGV)

$ ruby -roptparse -e 'ARGV.options{|opt|opt.on("--opt=ARG"){|@arg|};opt.parse!};p self,ARGV' -- --opt arg
#<Object:0x402de934 @arg="arg">
[]
