Just thinking that for the guide it would be nice to add a table to the #[pyproto] section listing all the dunder methods that can be implemented and the protocols they are a part of (e.g. __int__ -> PyNumberProtocol etc.)

Based on pythonnet/pythonnet#554

🐛 Bug Report

Recently, related to LLVM Loader, I've seen that there's some warnings with strlen and strncpy which were not present on my version of GCC ( metacall/core#137 (comment) ). This warnings indicate that there can be an out of bounds error or similar, so it should be reviewed.

Expected Behavior

No warnings shown.

Current Behavior

Currently, a Haskell program that reports uncaught exceptions in stderr looks like this:

main :: IO ()
main = withJVM [] $ handle (showException >=> Text.hPutStrLn stderr) the_program

The call to handle is cheap enough that it should be made inside of withJVM, making the default behavior the more chatty. Thus, the same behavior could be achieved with

main :
