python's twisted deferred : how to in Lua?

[Valerio Schiavoni <valerio.schiavoni@...>]

Hello,
the twisted python framework provides a very elegant mechanism to do
asynchronous programming, through so called 'deferred'.
See doc here: http://twistedmatrix.com/documents/current/core/howto/defer.html

I was wondering if there's support for this programming style in the
language itself (looking at the doc I don't think so), or if
something similar is provided by Lua frameworks.

thanks,
valerio
