everytime i'm using builtins i need to pull up the docs to check that i'm writing them in the right order and HALF THE TIME I'M WRONG

i really really hate inheritance!!! mainly for my specific use case. if i could "implement" an interface for types i don't own (i.e. python builtins here) it would be alleviated somewhat. even so, having anything resembling associated types play nice with type checkers has been an uphill battle too

This is run from Qwen 3.8 Flash 27B on my 64gb m5 max Mac Studio.
It is a real compiler bug, and it was a nontrivial fix across multiple programming languages.
I think this is wildly impressive for an at-home open weight piece of work

CVE-2026-120499 - h5io before 0.2.6 Arbitrary Code Execution via read_hdf5
h5io before 0.2.6 contains a code injection vulnerability in read_hdf5() that allows attackers to execute arbitrary code by supplying a crafted HDF5 file. Attackers can store Python code in a node titled timezone, which _triage_read() passes to eval() with builtins reachable, name an arbitrary module in class or custom-object nodes …

I think this hits the nail on the head. All of these abstractions (springs/struts, constraints, flexbox) work great until they don't, and then you're SOL
What I would have preferred is a layout system built on composable functions, where writing your own is no different from using builtins

after having done it in avril it's crazy how complex it is to implement support for npm packages . i think covering most node: builtins is gonna be a non-goal but i would love to be able to open a path to polyfilling them via avril:ffi but that means exposing some kinda pre-resolution module map
...node/npm support is removed? welp never using this then lmfao

I'm just trying to get the top values from an array constructed from a dictionary so I can go back to the dictionary and pull the names of the top 3 values, man.
Why are there no other sort builtins aside from ascending?
I just need to rebuild this array and get the first the indexed values!

I have now review all of stdlib at pythoncomplexity.com with Opus 5/5.5 or Fable 5.1 and GPT-6-Astra or GPT-6.1-Sol. Every stdlib module should now have tests (where possible) to back up the claims. Mostly Claude doing the work and Codex reviewing. Still working on builtins.
