Idiom #255 Print a set

Print the values of the set x to the standard output.
The order of the elements is irrelevant and is not required to remain the same next time.

for el in x do writeln(el);
System.out.println(x);

This produces a meaningful output only if the type T of elements properly overrides toString().
using System;
foreach (var el in x)
{
    Console.WriteLine(el);
}
