Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Monthly Hask Anything (August 2022)
Even the IfCtx "tricks" and stuff like /u/Noughtmare's post don't resolve the constraints at runtime. The constraints are still resolved statically, you just carry around a (constant) token that indicates how compile-time resolution went.
- Different `Num` instances based on availability of another instance.
- How do I define this super-unsafe type class (not internally consistent at all 😱)

Where's more discussion of the designs of effect systems?
Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.
