It's near the top of the `Nil` doc page you linked:

Any method call on `Nil` of a method that does not exist ... will succeed and 
return `Nil`.

Thanks

OK, that is intentional and documented then. What is actually the rationale for such a behaviour? For me it was an unexpected trap as I had a chain of methods which should do some side effect. It all went fine only the side effect was not there. I then figured out after some time that one of methods returned Nil and somehow silently it did not do what I expected.
