Great! Given that no function takes two Locations at once, a Location can be thought of (and implemented) as a record whose fields are "key", "before", "after", etc. To support this thought, it would be nice if all functions that take a Location as argument take it as the first argument. That seems already the case except in "assign". -- Edit this signature at http://www.digitas.harvard.edu/cgi-bin/ken/sig <INSERT PARTISAN STATEMENT HERE>
