I disagree that they’re like exceptions. Sure they share state but that’s not a core characteristic of exceptions. Contexts leave it up the consumer to decide when to care about state changes, something exceptions definitely do not. Contexts are complicated because concurrency is complicated. You can translate that complexity into other complexity like your Java example (to keep code idiomatic and unsurprising), but the intrinsic complexity doesn’t really go away. You can build higher level abstractions that add constraints on what you can do (eg structured concurrency) in order to hide the complexity, but that’s at a different abstraction layer than contexts.
