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 ?
