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).

How introduce `ResourceT` into my stack

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.
What are some alternatives?
parallel - a library for parallel programming
recursion-schemes - Generalized bananas, lenses and barbed wire
objective - Purely functional objects
lifted-base - IO operations from the base library lifted to any instance of MonadBase or MonadBaseControl
transient - A full stack, reactive architecture for general purpose programming. Algebraic and monadically composable primitives for concurrency, parallelism, event handling, transactions, multithreading, Web, and distributed computing with complete de-inversion of control (No callbacks, no blocking, pure state)
mmorph - Monad morphisms
foldl - Composable, streaming, and efficient left folds
Workflow - re-startable monad that recover the execution state from a log, and workflow patterns
auto - Haskell DSL and platform providing denotational, compositional api for discrete-step, locally stateful, interactive programs, games & automations. http://hackage.haskell.org/package/auto
ReplicateEffects - Composable replication schemes of applicative functors in Haskell
hask - Category theory for Haskell with a lens flavor (you need GHC 7.8.3, not 7.8.2 to build this!)
effectful - An easy to use, fast extensible effects library with seamless integration with the existing Haskell ecosystem.
