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.

My quest for the perfect AST representation
For the development of Lamdu I've embarked on a similar quest and ended up creating hypertypes after getting a helpful pointer in SO.
-
Extensible ASTs with extensible types
Otherwise I would go for modularity rather than extensibility and use hypertypes or an equivalent mechanism to represent the types.
-
What are strategies for tracking type checking errors after desugaring?
Indeed, then it is definitely possible. i.e https://github.com/lamdu/hypertypes
-
[ANN] rrb-vector - an alternative to Data.Sequence
Nice. Using this my type inference implementation benchmarked up to 2.5% faster and the switch wasn't difficult to do.
-
Hyperfunctions
I think https://github.com/lamdu/hypertypes might be related. This is a generic programming API that seems to be based on hyperfunctions, but moved up to the type level?
-
Handling an AST that is built from multiple types
I wrote an overview for several approaches folks came up with for this problem aka "the expression problem" including my own approach, "hypertypes" - see https://github.com/lamdu/hypertypes/blob/master/README.md
