Result<String, String> result = Result.of("Success!");
Result<MySuccessType, MyFailureType> result = Result.of(new MySuccessType());

Result<String, String> result = Result.fail("Something's wrong here!");

// Hint: use the var keyword to make the code more readable
var result = Result.of(new MySuccessType());
var result = Result.fail(new MyFailureType());Process a Result using the fluent API.
String result = Result.of("Success!")
.map(r -> "What a " + r)
.filter(r -> r.equals("Hello World!"), "Did not match")
.peekFailure(System.out::println)
.orElseGet(f -> f + ", but still a success!");
