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 (June 2021)

Friendship ended with Monads: Testing out Algebraic effects in OCaml for Animations
I would argue that the fact that not all monads compose is a feature, not a bug, in that not all effects are compatible. Citing from inotherwords:

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 fusedeffects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.
