Hot, fresh, and worth queueing round the block for.
Summary
The article critiques Python's list comprehensions, arguing that their syntax lacks ergonomic support for real-time coding assistance. The author illustrates this with an example where the editor fails to autocomplete or assist during the typing process due to the declarative nature of the syntax. The piece advocates for programming languages and tools that ensure code validity and editor support as it is being typed.
