I'm a bit hesitant to suggest this because you've been studying Ruby a long
time, and because I don't think I understand sufficiently what you want to
do. Do you want to do something like these:

class VarArgsExample
  def select_example_using_variable_args( *args )
    # now process the arguments to the method, for example
    args.each do |v|
      # do something with v
    end
    # maybe more processing
  end

  def select_example_using_array_arg( ary )
    # a similar idea works for a hash argument
    ary = [ary]  unless ary.kind_of?( Array )
    # now process the array values, for example
    ary.each do |v|
      # do something with v
    end
    # maybe more processing
  end
end

obj = VarArgsExample.new

obj.select_example_using_variable_args( 'apples' )
obj.select_example_using_variable_args( 'pears', 'plums', 'grapes' )

obj.select_example_using_array_arg( 'apples' )
obj.select_example_using_array_arg( ['apples'] )
obj.select_example_using_array_arg( ['pears', 'plums', 'grapes'] )
