I wonder if there could be a mechanism for reporting such cases.

" So and So issue detected. If you believe this is not a bug, send this Snippet or A ST as a bug report (If you want, we can do this automatically for you!)"

And also "We've detected so and so issue. Please see our wiki <link to specific issue> for an explanation on what may have triggered this, and for ideas on how to rewrite such code"

View on HN

"doubly linked list detected, this language does not support such constructs without 'unsafe' keyword being used to wrap it"

Which is why you implement a doubly linked list using data indices in a Vec<Node>. The resulting data structure is fully safe and resembles an ECS.

And features an extra level of indirection for your CPU's dcache prefetch predictor to trip over
