Yes, it's the same idea. As you can see, I did consider it at
one point, but I had second thoughts when I realised that it
wouldn't work through type slots, meaning that there would be
some areas of what appear to be pure Python code, but are not
suspendable for non-obvious reasons.
Maybe this is not a fatal problem -- we just tell people that
__xxx__ methods are not suspendable. It's something to consider.
