> Code reuse is in fact a prime example of a misuse of inheritance Does that depend on how inheritance works in a particular language? For example, in Python it’s widely believed that inheritance is simply “a tool for code reuse” [0].

I wish there were a language that I could use for both prototyping and production, but Go isn't it. Although I have been considering using it for production, it's not what I need in a prototyping language at all.

Usually, because you already have a lot of Python code and it's easier to write more of that, than to try and figure out Python <=> Java interop.

But Swift for Tensorflow had been doomed for over a year before it was cancelled - from when Chris Lattner left Google in January 2020.

Thanks - Alpine.js looks like an appropriate choice in general, but unfortunately it’s not supported by these particular components. However, the announcement does say “we're looking forward to exploring other frameworks in the future

The other issue with using PyInstaller to build a program into a single binary is that every time the program runs, it needs to extract its own contents to a temporary directory. This causes slow start-up and, if the program exits abnormall

It’s unfortunate that Go’s standard package `flag` doesn’t follow the standard either, given the language is otherwise a good fit for command-line tools.

GopherLua [0] is a Lua implementation written in Go, not just a wrapper around the reference implementation (written in C). The main alternative seems to be Shopify’s go-lua [1], given that Microsoft’s golua [2] is no longer being developed

Given their limited shelf-life, I’d have thought this would be less of an issue for games than for other software? Many games rely on Lua, for example, which is maintained by a team of just 3 people, and it seems only one of them writes mos

It doesn’t use the standard Ruby interpreter (MRI), but a custom implementation that includes a compiler. I don’t know if it’s AOT compilation or JIT.

It seems to be a custom implementation based on mruby and LLVM. See “What is DragonRuby?” at http://docs.dragonruby.org/ .

In Rust, some expressions (e.g. `while`) always evaluate to `()`. What’s the benefit of that compared to making `while` a statement?

> My main beef with Lua is the absence of ‘null’ Lua’s equivalent is `nil` - I assume that doesn’t do what you need? How would the behaviour of `null` differ from Lua’s `nil`?

There’s only 1 month left before the 3.10 feature freeze. I’d be surprised if the `match` statement gets anything more than minor tweaks before it’s released.

Variables in Python are generally function-scoped instead of block-scoped, because the latter doesn’t work well with implicit variable declarations. However, there are some special cases where variable scope is smaller than a whole function

> full of these sorts of interesting behavior I don’t think that applies to Python - it’s quite strongly (although not statically) typed. I agree that it does apply to JavaScript and PHP.
