I think any "inline function" proposal should focus on callback-based
programming for its use cases. In this context, you usually have one or
two callbacks (two in Twisted-style programming: one for success, one
for failure), passed positionally to a consuming function:
loop.create_connection((host, port), @cb, @eb) where:
def cb(sock):
# Do something with socket
def eb(exc):
logging.exception(
"Failed connecting to %s:%s", host, port)
Regards
Antoine.
