Hi all,
I just posted another essay on concurrent API design:

This is the one that finally gets at the core reasons why Trio exists; I've been trying to figure out how to write it for at least a year now. I hope you like it.
My experience is indeed that something like the nursery construct would make concurrent programming much more robust in complex cases. This is a great explanation why. API note: I would expect to be able to use it this way: class MyEndpoint: def __init__(self): self._nursery = open_nursery() # Lots of behaviour methods that can put new tasks in the nursery def close(self): self._nursery.close() Also perhaps more finegrained shutdown routines such as: * Nursery.join(cancel_after=None): wait for all tasks to join, cancel the remaining ones after the given timeout Regards Antoine.
