MochiKit
Closure
jQuery

I'd be interested in baking a JS Deferred which

I follow Glyphs advice and only keep the lambda version with standard Twisted
Deferred.
However, I've got a (I believe) more serious design problem.
The RPC stuff works in Twisted, but also from JavaScript.
So I have 2 audiences (Twisted and JS developers).
On JS, I use the Deferreds that
No, this is something jQuery and CommonJS got wrong; callbacks don't chain
in their implementation.
Firing a jQuery promise invokes each callback in order with the same
argument. Firing a Deferred in Twisted invokes the first callback then
passes its return value as the arg to the next callback,
Ok. This is most unpleasant. In particular since my options then are:
1) write my own, sane (Twisted like, which I think is the sane way) JS
deferred, not use jQuery/CommonJS (which everyone else does)
2) open the door for users running into issues when they do both Twisted
JS/jQuery and don't
As far as I know, Dojo's Deferreds are a direct port of Twisted's.

My understanding (partially aided by this post:
http://www.sitepen.com/blog/2010/05/03/robust-promises-with-dojo-deferred-1-5/)
is that Dojo provides both twisted-style addCallback and
CommonJS-style
then methods.

I am still wondering why they called the other stuff then() when it's not

I agree. I had the same frustration a few months ago and various

Jasper, Allen, Richard,
thanks all for the pointers. I am confused now;)
No, seriously, I need to _test_ those libs, to see what they actually do.
I.e. I suspect the new Dojo Deferreds with then return something
different than the broken then in jQuery 1.5.
This is all messy, personally, I

Note that as far as I know, MochiKit isn't actively developed anymore.
Google's Closure has a fork of MochiKit's Deferred's, which seems to
incorporate some of Dojo's code as well.
