+/// Fuzz a closure-like block of code by passing it an object of arbitrary type.
+///
+/// You can choose the type of the argument using the syntax as in the example below.
+/// Please check out the `arbitrary` crate to see which types are available.
+///
+/// For performance reasons, it is recommended that you use the native type `&[u8]` when possible.

+/// ```rust,should_panic

+/// # fn main() {
+/// fuzz!(|data: &[u8]| {

+///     if data[0] != b'q' {return}
