tasklet library based on PEP 0342

[charlie137]

Hello all,

Using new features of python generators, as described in PEP 0342, it
is possible to write some sort of "tasklets" in a maner very similar
to stackless python, but running on cpython. For example :

@tasklet
def my_task():
yield Timer(10)
yield "result"

@tasklet
def other_task():
result = yield my_task()

other_task().start(callback=on_return)


I wrote an implementation of this in the scope of an open source
project for openmoko [0], there is also an other very similar
implementation from the kiwi project [1].

This kind of tool is very useful, but unfortunately there is no
standard library that would provide a unified way to use it
independently of the underlying event loop.

Does someone know if a similar library could eventually be added into
python standard libraries ? Would it be accepted as a PEP ?

Start by listing your module/library on http://pypi.python.org/pypi
To ever get in the stdlib, it must be tested, used by several different
people, the best of its type, and relative stable.

I am afraid my implementation passes none of those requirement.
I will send a message to the python idea mailing list though. Thanks
for the answers.
