Most of that is a *massive* YAGNI as regards function default arguments. We do not need parallel execution just to figure out the length of a list passed as a previous parameter. So you've just added weight to my argument that a generic "delayed" feature is a completely separate proposal, nothing whatsoever to do with PEP 671.
