> I think being able to take and return futures or promises and handle them how you wish is better ergonomics. You can do that. If you don't await an async call, you have a future object that you can handle however you want.

I'd argue that it is. Use const by default, so it's obvious to the reader if something is mutated or not. It's easier to read code when you don't have to worry about how values may change over time. This is why Rust made

By "the goal", I mean TFA's, not JS's.

There are [1] and [2] for function arguments and loop variables, respectively, but nothing for the general case. Note that a type checker will complain if you re-assign with a different type. Pylint also has [3] for redefining variables fro

Because this isn't immutability. The goal is to have a way to define an object that will never change after initialisation, and JS's const isn't it.

How isn't it transitive in C++? If the variable/reference is const, you can't modify fields, and you can only call const methods. What else do you need?

Not "a resource", but memory specifically. If there's a proper resource (e.g. a file), you should ensure it's explicitly released instead of relying on the GC (using with/close/etc.) And if memory usage is real

> But it's a little too verbose to just sprinkle on every variable in C++ It's worth it, though. Every variable that isn't mutated should be const. Every parameter not mutated should be const, and so should every method th

This is only for redefinitions that change the type. If you re-assign with the same type, there's no warning. However, pylint does issue warnings for other interesting cases, such as redefining function arguments and variables from an

Good old Gell-Mann Amnesia! It doesn't mean he's incompetent in his core area of expertise, though.

JS's const doesn't go far enough since you can still mutate the object via its methods. In C++, you can only call const methods (which can't mutate the object) on const variables.

Many developers are on Windows, and those tend to prefer GUIs. CLI reliance is mostly a macOS/Linux thing.

I generally agree with you, but this is a poor take. Developers, in general, like to write code. Writing prose is incidental. If the job becomes writing prose instead of code, it's easy to see why there's pushback.

Sometimes dynamic Python idioms are incompatible with typed Python. I personally think that's fine, since I consider static typing a significant improvement overall.

I imagine Pycharm would still be better at refactoring (extract method/variable, in-line variable, etc.) LSPs are good at renaming, but not much else. There's a plug-in, but it breaks very often.
