I understand that this is mostly a matter of taste in API design, but IMHO 
that's an anti-pattern. It encourages poor style; it discourages 
functional programming patterns, instead favouring state mutation 
patterns; it makes APIs harder to extend; it makes APIs that do have 
useful return values inconsistent with other APIs; it is, in fact, a 
layering violation: it attempts to shoehorn what should be a language 
design feature into the API layer.

But I'll leave it up to the DOM guys to decide what to do for that 
interface. :-)
