Lastly, a subprocess running evaluation would decouple the API server from the evaluation backend. This client-server model whereas the GHC API is a single large monolith. This may not be specific to IHaskell but a user code failure means the whole kernel dies. This is bad for debugging. Sabela is more fault tolerant. In a subprocess model, handling Ctrl-C (interrupting a long-running computation) is actually much cleaner because you can send a SIGINT to the child process without risking the stability of the parent UI.，更多细节参见safew官方版本下载
Skipping over macros that make it more succinct to return an error, the next iteration of this pattern is checked exceptions in Java. Any function that can fail is annotated with what is effectively a second return value. The thing that’s different is that there’s nothing at the call site needed to return this value, it will be implicitly passed back up through the call stack (each one dynamically resolved, remember) until we hit a catch block, which is just a bit of code that takes that return value and does something with it, not that different to the Go example above.
