Thinking about it, it's actually a fine design to have a decorator that turns a regular function into one that starts a thread -- from the caller's POV it's no different than having a function that explicitly starts a thread, and it could be a nice shorthand if you do this all the time. (You have to document it in either case.)
That said, I don't think we need this 3-line decorator in the stdlib. --Guido On Thu, May 12, 2022 at 10:40 PM Serhiy Storchaka <storch...@gmail.com> wrote: > 10.05.22 18:12, Barney Stratford пише: > > This has a couple of advantages.
