Classes over methods?

gistfile1.txt

# SomeClass.new("arg1", "arg2").call
class SomeClass < Struct.new(:arg1, :arg2)
  def call
    @arg1 + @arg2
  end
end

# vs

# SomeClass.new.some_method(arg1, arg2)
# instance.some_method("arg1", "arg2")
class SomeClass
  def some_method(arg1, arg2)
    arg1 + arg2
  end
end
