i prefer

   define_method 'method_name' do |required, *optional|
     one, two, *ignored = *optional
   end

because you an error will be thrown if required is not passed and you  
don't risk slurping ten arguments into 'two'

alternatively just use a hash

   define_method 'method_name' do |required, *options|
     options = options.first || Hash.new
     foobar = options[:foobar]
   end

   method_name 'required'
   method_name 'required', :foobar => 42

kind regards.
