Fire up your favorite search engine, type in “mutable value types” and you might just feel a bit of pity for the poor little guys. It seems like everyone hates them.

In an effort to release simple, streamlined APIs, we spend a lot of time poring over every aspect of our types.One of the types that we know is getting used a lot both internally and externally is LazyInit<T>.  One of LazyInit<T>’s constructors takes in a LazyInitMode enum which allows you to initialize a value in one of...
