Hi Sebastian,
I know that it's more or less syntactic sugar but I don't see the negative effects. Setters already do return values. They return the new value of the property but I don't know if anyone uses it to returning this would be more reasonable.

Betreff: Re: [qooxdoo-devel] Suggestion: Chaining setters
Hi!
If I remember correctly this was already discussed previously on this
list. It has to many negative effects. Generally this means it's not
anymore possible to return null or just make it undefined. Also it's
maybe a performance impact to always return a value where currently
there is no return at all.
I think the alternative shown by Alex is easy enough:
object.set({ foo : 20, bar : 100 });
-1 ;)
