error: non-binding let on a type that implements `Drop`
--> $DIR/box_vec.rs:7:9

LL | let _: Box<$x> = Box::new($init);

...
LL | boxit!(Vec::new(), Vec<u8>);
| ---------------------------- in this macro invocation

= note: `-D clippy::let-underscore-drop` implied by `-D warnings`
= help: consider using an underscore-prefixed named binding or dropping explicitly with `std::mem::drop`
= note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)
error: you seem to be trying to use `Box<Vec<T>>`. Consider using just `Vec<T>`

= help: `Vec<T>` is already on the heap, `Box<Vec<T>>` makes an extra allocation.
