I haven’t kept up with python too much over the past year or two and learned a couple new things from this code. Namely, match/case and generic class typing. Makes me wonder what else is new, off to the python docs!

    thanks for pointing that out. Seems a thorough scan as features of whatsnew is due - since maybe 3.7?

    For the record, ~language~ additions i found interesting (excluding type-hints):

      3.11:
   (Base)ExceptionGroups ; (Base)Exception.add_note() + __notes__
   modules: tomllib
  3.10:
   Parenthesized context managers 
   Structural Pattern Matching - match..:case.. 
   builtins: aiter(), anext() 
  3.9:
   dict | dict ; dict |= dict
   for a in *x,*y: ...    #no need of (*x,*y)
   str.removeprefix , str.removesuffix
   Any valid expression can now be used as a decorator
   modules: zoneinfo , graphlib
  3.8:
   Assignment expressions
   Positional-only parameters
   f'{expr=}'
   Dict comprehensions and literals compute First the key and Second value
  3.7:
   builtins: breakpoint()
   __getattr__ and __dir__ of modules
   modules: contextvars , dataclasses

      Misc:

      3.10 zip(strict=True) 3.11 asyncio.TaskGroup (structured concurrency) enabled by ExceptionGroup

      3.12 itertools.batched(L, n) — it replaces zip([iter(L)]n)

It's 736 LOC now.

    That is counting all comments and empty lines, which are many.

    If you count only the library code, it is less than 250 LOC.

    I then asked for Claude to write the docstrings and examples which increased by 500

      It reminded me of pycon talk by David Beazley - Python Concurrency From the Ground Up: LIVE! - PyCon 2015 https://www.youtube.com/watch?v=MCs5OvhV9S4

      What is the purpose of @dataclass on Task class?

        No purpose. I think I added in the initial implementation and ended up not being required, but I forgot to remove
