[Haskell-cafe] Taking over maintenance of int-cast package

I intend to take over int-cast (https://hackage.haskell.org/package/int-cast) package. I think it implements a reasonable approach to ensuring compile-time safety of integer casts, and it would be sad to see it silently fall into obscurity due to the lack of maintenance. This was discussed on GitHub (https://github.com/haskell-hvr/int-cast/issues/5#issuecomment-1620402453) since July 4, 2023, and I tried reaching @hvr via e-mail on July 5. Didn't receive a reply at the time of writing, and it seems unlikely I will anytime soon, hence moving on with the takeover process. This message is cross-posted to Haskell Discourse (https://discourse.haskell.org/t/taking-over-maintenance-of-int-cast-package/...)
