Make closures and generators a must use types Warn about unused expressions with closure or generator type. This follows existing precedence of must use annotations present on `FnOnce`, `FnMut`, `Fn` traits, which already indirectly apply to closures in some cases, e.g.,: ```rust fn f() -> impl FnOnce() { \|\| {} } fn main() { // an existing warning: unused implementer of `std::ops::FnOnce` that must be used: f(); // a new warning: unused closure that must be used: \|\| {}; } ``` 2020-07-28 00:00:00 +00:00			`{\|i: u32\| if 1 == i { }}; //~ WARN unused closure that must be used`
