Random idea for web standards people:
An interesting test of a written standard is an implementation. Since we now seem to be living in a world where prototypes are made quickly (AI) one could request such an implementation and view confused interpretations as an opportunity to clarify.

When one needs to understand the build system to answer questions about outcomes that’s significantly easier for deterministic pipelines.
Similarly, I see this same argument made wrt compilers but it is possible to say what a compiler should do to be correct, that’s not true for an LLM.

this is exactly right and explains why most handwringing about building systems we don’t understand is misplaced. pre-LLM software engineering already consisted almost entirely of building systems we did not understand
Nobody knows how the whole system works

Whenever UB is discussed I rarely ever hear about the reason why it exists and why it’s good: it’s how the compiler tells you about assumptions it needs for optimizations you almost certainly like a whole bunch.
Best modern example is stacked/tree borrows in Rust unsafe regions.

There’s also clearly an interesting opportunity to hook up CSmith in a tight loop with the output here to see how well it responds to feedback about output discrepancies

Now imagine that we could convey what a correct compiler is in a useful way for this process to leverage. The statement is complex if you care about optimization but it does exist as math.

New from Anthropic: “Including ads in conversations with Claude would be incompatible with what we want Claude to be: a genuinely helpful assistant for work and for deep thinking.

my luke warm take is that if people knew what it meant for a compiler to be correct the broader idea of “abstraction” would be much clearer since its usually the first example they encounter
note for nerds: this conflates abstraction/refinement with “less detail” which are not necessarily the same
