"The downside is less development and deployment flexibility, but it offers several advantages. For one, it creates optimisation opportunities at compile time via static program analysis." Optimisation. This is a smart move, hard though. A compiler, written well allows the back end to improve the code. So the whole code base can improve with improved analysis. "The biggest advantage is that interoperability with Go code becomes very powerful and straightforward: Grumpy programs can import Go packages just like Python modules!" Extending Python (youtube codebase) with Go modules. That's interesting.
