Whereas if I could wrap up yield, I simply have to do:

item = waitForSomethingCheckingPeriodically()
process(item)

Which if I have lots of this sort of thing going on, results in much
clearer (and hence maintainable) code.

If it can't (putting yield in a function, and not turning the function into
a
generator) be done, and AFAICT it can't, and this is a suggested work
around - many thanks :-)

Best Regards,


Michael.
