The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

- Haskell is the greatest programming language of all time

Implied bounds and perfect derive
Isn’t this what Haskell’s backpack does? https://github.com/danidiaz/really-small-backpack-example
-
Polymorphic unpacking through backpack?
Also worth mention how module identity works in Backapck: two modules instantiated separately but with the same ingredients are "equal" and have compatible types.
-
Using dependent types to write proofs in Haskell
Anyway, an alternative to RULES that I've explored is to put the proofs behind a module signature and compile to versions of the program, one with "real" proofs and another with unsafeCoerced ones. This avoids the danger of the RULEs silently ceasing to apply because of name changes (don't know how common is that danger in practice though).

Video Tutorial: "Using proofs to make functions faster over length-indexed vectors" (Richard Eisenberg)
Here's an example of how to use Backpack (instead of rewrite rules) to alternate between "normal" proofs and the ones which use usafeCoerce.

Proposal for parametric modules like Coq's?
Perhaps Backpack could enable something similar to that?

While being nowhere near programmability, Cabal's common stanzas can be very useful to reduce duplication. An example.
