+### What it does
+Checks for `let _ = <expr>` where expr is `#[must_use]`
+
+### Why is this bad?
+It's better to explicitly handle the value of a `#[must_use]`
+expr
+
+### Example
+```
+fn f() -> Result<u32, u32> {
+    Ok(0)
+}
+
+let _ = f();
+// is_ok() is marked #[must_use]
+let _ = f().is_ok();
+```
