naming-conventions

I know there is __FILE__, __LINE__, and __send__.

From the Delegator class there are __getobj__ and __setobj__.

Is there any other useful "strange" double underscore goodness present in the Ruby standard library?

Additionally, Ruby allows the combination of both underscore and asterisk which is especially useful when you need for instance the first and last element from an array.
