+We have a bunch of lint categories to allow you to choose how much clippy is supposed to ~~annoy~~ help you:
+
+* `clippy` (everything that has no false positives)
+* `clippy_pedantic` (everything)
+* `clippy_style` (code that should be written in a more idiomatic way)
+* `clippy_complexity` (code that does something simple but in a complex way)
+* `clippy_perf` (code that can be written in a faster way)
+* **`clippy_correctness`** (code that is just outright wrong or very very useless)
