New submission from Yury Selivanov:
1. aclose() should not propagate StopAsyncIteration:
async def agen():
try:
yield
except:
pass
gen = agen()
await agen.asend(None)
await agen.aclose() # <- this shouldn't raise StopAsyncIteration
2. athrow() should propagate StopAsyncIteration when the exception was
swallowed by the generator and it returned:
async def agen():
try:
yield
except:
pass
gen = agen()
await agen.asend(None)
await agen.athrow(ValueError) # <- this should raise StopAsyncIteration
