What do you mean by 'chaining'? Twisted's Deferreds provide at least a couple of things one might casually describe as 'chaining'.

Instead of:

  d.then(func1);
  d.then(func2);
You can use:
  d.then(func1).then(func2);

Ah, yes. Twisted's Deferreds do support that kind of chaining, but I didn't use it in my original snippet because I didn't want to have an example of a Deferred where no Deferreds were actually visible. :)

In my own code, I tend not to use chaining because "methods returning self" is not a common idiom in Python (although tools like jQuery have given it currency in the JS world) and because I haven't yet figured out a way of formatting a multi-line method invocation that doesn't look messy.

as you can do in twisted ;)
