What are the `@` characters for? Are they what makes it feel like Perl? Because other than them I don’t think the equivalent Python code would look much different. Maybe more concise, e.g. you could replace the second section with something

At least Microsoft hired a bunch of experienced Python core developers for their effort. IIRC Unladen Swallow was just a couple of interns.

> Python aims to be simple Well, it wildly missed the mark there. Nothing about modern Python is simple. It's a very complex language hiding behind friendly syntax.

There’s been a lot of hype around Mojo, but is anyone actually using it? Does it deliver on the bold claims of its designers?

The community basically did reject Python 3, at first. Almost nobody used 3.0 / 3.1 / 3.2, to the point where I’ve seen them retconned as beta releases. Even then though, the core developers made it clear that breaking everyone’s

The “Faster CPython” team were let go from Microsoft because they could only produce a 1.5x speedup in four years instead of the planned 5x. It’s wildly optimistic to now expect a 10x speedup in two years, with fewer resources.

I sometimes wonder if many core Python people don’t actually like the language that much. That’s why (a) they’re constantly reinventing it, and (b) they celebrate rewrites from Python into other languages. Long before Rust, it was considere

Your `name` getter isn't working properly. Weirdly, Wren's implicit returns only work for functions written on a single line. The getter either needs to be (exactly) `name { _name }` or it needs to explicitly `return _name`. http

Wren does have instance method inheritance. It's implemented differently from most scripting languages, though. The implementation is more like a statically-typed language, for performance reasons: https://wren.io/perfo

Yeah, my understanding is that the bytecode interpreter in the second half of the book is essentially a stripped-down version of the Wren virtual machine.

Yeah, Lua's implementation is fantastic - but the language is "quirky" at best. Wren looks a bit more orthodox, although it's heavily built around class-based OOP - you can't even define and call a top-level functio

I think I read that Wren's creator deliberately avoided "the metaclass hierarchy matches the class hierarchy" (as used in Smalltalk and taken to an extreme in Ruby [0]) because the authors of Smalltalk have come to regret tha

I thought one of Lua’s selling points is that it’s written in highly standard-compliant C code. I wouldn’t expect it to do anything non-portable like bitwise manipulation of pointers?

Python is not simple, it's a very complex language hiding behind friendly syntax. Given that, plus the breadth and complexity of its ecosystem, it makes sense that its tooling is also complex.

I did some recent testing that showed both Lua and LuaJIT-joff (its interpreter-only mode) to be about 2x faster than Python. Both PyPy and full-on LuaJIT were about 10x faster. Years ago, I even found Ruby to be faster than Python. This wa
