Not sure what you mean here. How does an implicit context change any semantics? You would still be able to override which context is given to goroutines you spawn. As a developer, you'd have to be aware of the implicitness, that's the only difference.
- riwsky 8y agoI agree it doesn't change the semantics, and that you can express the same set of programs (given that you still let people explicitly handle contexts, send them over channels, etc). I just mean to highlight that removing context-usage information from go function signatures does not mean that usage or non-usage of context isn't part of a function's API—it's just now global state, and needs to consider its interactions with everything else in the same routine (instead of everything lexically in scope).
