Remove unused contexts #34
Description
What is the problem this feature would solve?
When I use Effect's Context, it's easy to know when a context is missing as there is a compiler error without adding an Effect.provideService for example. If that context is no longer needed though, nothing tells me I can remove that code other than being vigilant. Similarly if the return type to my function is an Effect with a context that is unused, nothing enforces that I remove the context on my return type.
What is the feature you are proposing to solve the problem?
It'd be great to have a linter rules that can ideally automatically remove unused contexts, or at least flag them for me to look at and decide whether to remove manually.
What alternatives have you considered?
I looked around a little for a similar rule but couldn't find one. I'm no expert at custom EsLint rules to know if this is possible, but it'd be great if it was!
