It doesn't fit the requirement to modify the list in place, but the prompt itself contradicts the requirements by asking explicitly for the implementation to use *args and a list comprehension.
Ahh I didn't see the full original prompt -- it's overflowing into a horz scroll for me. I thought it was the "critique loop" that injected the *args requirement. I guess garbage in, garbage out. Still unfortunate example to use.
Oh I wouldn't be surprised. This is a sample from one of the OSS code datasets I'd used, which are all generated synthetically using LLMs. Data is indeed the moat.
