Is There a Way to Make Your Code Fast?

In general, avoiding the dynamic type is going to help. But for the most part, your dark code is already not using the dynamic type. It's most of the time using type inference and giving you the correct static type anyway. So you don't usually have to think about that very much. And if you do find hot spots, then those places maybe make your coat a little more verbose or reared in some patterns that make it faster.
