You’re not wrong, but the very first lines of asyncio.gather wrap the supplied arguments with create_task if they’re not already Tasks.

Not GP but off the top of my head: async cancellation, mutex poisoning, drop+clone+thread interactions, and the entire realm of unsafe (which specific language properties no longer hold in an unsafe block? Is undefined behavior present if t

GP didn’t say “setting a ‘bool’ value to true”, it referred to setting a “field”. Interpreted charitably, this would be done in Go via a type that does support atomic updates, which is totally possible.

Strongly agree. A language which has something like “wantarray” as a first-class feature is semantically…unique, at best, probably more like “flawed by design”. All the oddness with typing and sigls descends from that. Same for autovivifica

Correction on my first bullet, regarding tagged pointers. The link was wrong (mistaken duplication of the link used above), and the tagged pointer optimization is not present in CPython, but only in PyPy, so it largely does not pertain to t

That’s a good argument. I had not considered properties in those terms before, and have historically been skeptical of them in many languages. I’m partly convinced now! I still worry a bit about property authors who don’t follow the “cheap,

What about TLS versions? Or tabs, way back in the day? Or security warnings/prevention for CORS? All of those were, as far as I know, enabled by default and released in browser updates.

Sure, surgery and several other risky and/or invasive treatments. Or you could take statins and prevent it from becoming an issue in the first place.

How so? Genuine question. Duck typing is “try it and see if it supports an action”, where interface declaration is the opposite: declare what methods must be supported by what you interact with. In Python, that would be a Protocol ( https:&

Yeah, spelunking around this is a great way to learn a language! That said, “is an object” is a bit of an overloaded term in this context. Most things in Python can be semantically addressed as objects (they have fields and methods, “dir”

Taking this more seriously than it perhaps deserves: if that’s true, why isn’t widespread adoption of this approach growing? Whether or not it’s a good idea, “realistic” implies practicality, which could presumably be measured by whether pe
