Michael Howell	2df14c3701	Add a lint to warn on T: Drop bounds ... **What it does:** Checks for generics with `std::ops::Drop` as bounds. **Why is this bad?** `Drop` bounds do not really accomplish anything. A type may have compiler-generated drop glue without implementing the `Drop` trait itself. The `Drop` trait also only has one method, `Drop::drop`, and that function is by fiat not callable in user code. So there is really no use case for using `Drop` in trait bounds. **Known problems:** None. **Example:** ```rust fn foo<T: Drop>() {} ```	2019-02-17 22:53:08 -07:00
