I don't think this is too difficult to explain.
The problem lies in the mistake of trying to do an action on one that
does not receive such action.
They want to split an array. You cannot split an array, an array is
already split. You want to split a string. This could have simply been
a typo. If they would, for instance, do (under vim) :%s/@argv/$argv/g
everything would be okay.
