// # Fuzzing
//
// 'go test' and the testing package support fuzzing, a testing technique where
// a function is called with randomly generated inputs to find bugs not
// anticipated by unit tests.
//
// Functions of the form
//
//	func FuzzXxx(*testing.F)
//
// are considered fuzz tests.
//
// For example:
//
//	func FuzzHex(f *testing.F) {

A fuzz test is one named FuzzXxx and should have the signature,

	func FuzzXxx(f *testing.F) { ... }

An example function is similar to a test function but, instead of using
*testing.T to report success or failure, prints output to os.Stdout.
If the last comment in the function starts with "Output:" then the output

// removing objects that they create. That would avoid name-collisions.
