Does Java 8 provide a good way to repeat a value or function?
... .forEach(System.out::println);
If you need a step different from 1, you can use a mapping function, for example, for a step of 2:
IntStream.rangeClosed(1, 8)
.map(i -> 2 * i - 1)
.forEach(System.out::println);
Or build a custom iteration and limit the size of the iteration...
Read text file into string array (and write)

As of Go1.1 release, there is a bufio.Scanner API that can easily read lines from a file. Consider the following example from above, rewritten with Scanner:

python max function using 'key' and lambda expression
...ax(players, key=func)
But as def statements are compound statements they can't be used where an expression is required, that's why sometimes lambda's are used.

However, it's worth noting that (ironically) json_encode performs noticeably faster:
md5(json_encode($array));

To not waste compile time and object file size, there is an extern keyword which makes the compiler not compile a template function. You should use this if and ...
