Well, depends on how you want to go about signifying a 'null' value. Recall that an empty string is both defined and a common way of indicating that variable holds no useable value. So, calling the method like foo('') will effectively unset the variable. Of course in more complex situations (i.e., where the value to be set is an object reference, not just a string) you'd need something better, probably something along the lines of your suggestion to pass undef as a parameter.
