Terminology is a problem and “scope” is already overused.
Yes, that really sucks. We should come up with something less generic than “scope” or “bundle” and less arbitrary than “nursery”. Also, being a core concept the name should be two or less syllables long.
After spending some time browsing the thesaurus I’ve found “twine”. It represents the concept well (it’s a collection of threads), it’s 1 syllable long and most importatnly, the name is not already taken. Would that work for other people here?
There are a few other concepts such as nesting and a “non-cancellable” scope to shield fibers from cancellable during recovery, cleanup or critical operations. This may be relevant to some of the discussion here.
I’ve made a separate post about this topic here (Graceful Shutdown - #3 by sustrik) but I think that what I’ve wrote is not easy to grasp. I’ll try to write a blog post about the topic or something.
