for `Box<FnBox()>`. I found the alias was still handy because it is shorter than the fully written type. This is a [breaking-change]: convert code using `Invoke` to use `FnBox`, which is usually pretty straight-forward. Code using thunk mostly works if you change `Thunk::new => Box::new` and `foo.invoke(arg)` to `foo(arg)`.
