While this works, it's not immediately readable and creates confusion. Mis-using Swift's control flow. Did not pass code review.

Explanation: This can't be null in C# virtual instance methods - I was so confused by the widespread use of this check that I asked this question at SO: https://stackoverflow.com/questions/31747718/can-this-be-null-in-c-sharp-virtual-methods-what-happens-with-the-rest-of-ins

The for loop that counts to 10, but the last seven elements are completely useless.
