IIRC stackless python implemented microthreads and channels before go existed - thats the whole point of stackless python - so whats the benefit here on top of that?

The benefits to new frameworks based on Stackless are obvious if you use Stackless.
It's really quite a simple library, as all the hard work is done by gevent/stackless and most of the hard API decisions were copied from Go. I'm not smart enough to invent this stuff from scratch!
Yes, these things have been used in the past. No-one denies that, and there are copious references where Stackless was based on Limbo. Every time something new comes up which uses old technology, there's always those who have to assume it means that it insults the old adopters in some way. Or that fealty has to be paid to the old adopters. At some level this becomes tiresome and unhelpful.
It would help, if those promoting the new old technology would present it as bringing back something from the past, instead of a magic new technology.
