When ever I think I can use the yield keyword, I take a step back and look at how it will impact my project. I always end up returning a collection instead of yeilding becau
Note that yield allows you to do things in a "lazy" way. By lazy, I mean that the evaluation of the next element in the IEnumberable is not done until the element is actually requested. This allows you the power to do a couple of different things. One is that you could yield an infinitely long list without the need to actually make infinite calculations. Second, you could return an enumeration of function applications. The functions would only be applied when you iterate through the list.
