It would be nice if we could get automatic memory management for blocks as well, instead of having to specify returned blocks as *mut Block<dyn Fn()>, and then converting those with RcBlock::copy.
If I'm reading the ARC spec right, it seems like blocks are actually autoreleased according to (mostly) the same rules as other Objective-C objects, and that we need to use objc_retainAutoreleasedReturnValue to access returned block pointers?

objc_retainAutoreleasedReturnValueto access returned block pointers?A few examples of more complex memory-management:
-[NSBackgroundActivityScheduler scheduleWithBlock:], an example of a block taking a block as a parameter, which is kinda interesting.NSProgressPublishingHandler, an example of a block returning a block.-[NSError userInfoValueProviderForDomain:], an example of a method returning a block.Also, should blocks be allowed in
Id?
