I'll say. For myself, I have mixed feelings - very powerful, but
a little scary. I was able to set up a callback-driven system that
uses continuations to span callbacks in a single function - like,
# callback from UI - selected login option
name = self.config.loginid
password = self.getpassword(name) # posts password prompt window
# Function actually returns from callback ...
# ... New callback arrives with password requested here; continue!
That's arguably more readable than any alternative I ever thought of,
but then it substantially obscures the "real" flow of control in the
program. Anyway, whether I want to go that way or not (and I don't
know for myself), it clearly is indeed a meaningful advance, something
that makes a substantial difference in what you can do with Python.
Definitely worth looking at, if you have gnarly asynchronous programming
