Hi Curtis, All functions in String accept a string only as first argument, so I would be wary of making an exception. We could perhaps allow it in Integer.parse/2 but I am not sure if we should make an exception there either, especially when we consider there are other arguments such as base and what they should mean when an integer is given.
