> No types
It's pretty easy to add types to Python nowadays. I'd consider it bad practice not to do so in a large project.
It would be nice if python would show types in the documentation. Not only do I need that all the time, it would show python was taking type safety serious.
For example, knowing the return type of a function is Union[DataFrame,Series] rather than simply DataFrame would save a lot of bad errors.
Wasm faster than containers? I guess they mean under there specific circumstances. Rust or C on a Linux container running machine code should definitely be faster than Wasm bytecode.
