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.

UnliftIO, ExceptT and Coercible
FWIW, your suggestion is very similar to a proposed instance for MonadUnliftIO (ExceptT e), except that effectfuls use of the type system means that it doesn't suffer from one of the proposed downsides (dubious interaction with catchAny).

Is `MonadBaseControl` dead?
Any way quoting u/snoyberg : https://github.com/fpco/unliftio/issues/17#issuecomment-363655106

Try.do is dangerous
That's not true. It's just writing that instance is a bit tricky: https://github.com/fpco/unliftio/issues/68

Try.do for recoverable errors in Haskell
However, ExceptT cannot be an instance of MonadUnliftIO – because it necessarily requires multiple exit points. See this discussion which should give you an idea of how hairy and unpredictable this can be.

Is `MonadBaseControl` dead?
Then I found Snap has a MonadBaseControl instance, and thought it should work for me. But sadly to find it losing states. Also I failed to find a user side example of MonadBaseControl on Github (as there're only instance impl. hits), so I have not way to verify whether that's due to my incorrect usage.
