[New-bugs-announce] [issue32104] add method throw() to asyncio.Task

[Oleg K]

New submission from Oleg K <windspirit at gmail.com>:

currently there is no other way to interrupt task but to call
cancel() which will: 

"This arranges for a CancelledError to be thrown into the wrapped coroutine on the next cycle through the event loop."

in order to write advanced Tasks there should be a way
to throw custom exceptions into active Task. 
so it can react accordingly.  

i am looking for the same thing as "generator.throw()" is providing,
allowing to interrupt generators different way.
