For example:
stdin.byLine.array;
Will give you an array of the same string. Although this is the correct behavior, it will surprise someone who is new to the language.
I think we should make byLine duplicate the string by default.

The solution is to use byLineCopy.
I think it's to late to change the default. Only the documentation can be improved.
