Mozilla already had to solve this problem for XMLHttpRequest, which  
has methods with optional arguments on e.g. the open() method. What  
approach did you guys take? (More so than the current case at hand,  
which I think is out of scope for SVG anyway, I'd like Web API to  
handle this properly when writing the spec for XMLHttpRequest).
