aliases in ROR (for an instance)

Shai :

and i want to rename/alias method1 to method_one, so that
eventually i will be able to do

@item.method_one # returns @item.method1

...is there any kind of command to change the instance_methods'
aliases? something like

alias_instance_method :method_one :method1

You can use the class singleton of @item object :

class << @item
  alias :method_one :method1
end

then you can do @item.method_one
