There's no proper language feature to catch these problems, so they've been relegated to Clippy. This approach doesn't work well:
[Clippy] also complains about a million other things, including the fact that I write numbers as 1000000 and not 1_000_000. There's something about errors and warnings, but some of my other stylistic atrocities like single iteration loops are marked as errors as well. I used it for a while, but generally found it too tiresome.
If there's an error which is a clear cut bug, I think it should be reported by an error detecting tool, not a linter.
Could some of the most serious Clippy lints be moved to
rustc itself? So that they're always run, and always watch out for these bugs?
