Unless there is some driving need (convenience is a need :) to use
dynamic names, you could do this:

objs = List.new     # [] works too
10.times { |i|
   objs << Test.new('give me', 'some parameters')
}

Objects created this way could be accessed in the list like this:

objs.each { |ob| ob.mymethod( arg1, arg2) }

or maybe

objs.each { |ob| 
  if( ob.changed? )
    # do something
  end
}

... and if you need to access an individual object in the list

objs[5].mymethod(arg3, arg4)
