On the cost of being lazy

Full source code can be found here

Changelog

2017-01-04
New performance test - Paul Westcott (@manofstick) provided his implementation of Lazy semantics (called Lazzzy) which I included in the graphs. This implementation is intended to be equivalent to Lazy<'T> in .NET with regards to functionality.
2017-01-17
New performance test - is working on a PR for .NET Core. I wanted to include performance numbers for the updated Lazy<'T> class.

Why my F# projects don't use RavenDB, or the cost of the esoteric choice

As you know, I generally recommend using SqlServer for data storage.

But many people have suggested that using RavenDB rather than SqlServer would dramatically reduce the development effort.

My reply to that was that using RavenDB would also lead to a lot more complexity, reduced support by other teams, harder to find DBAs and increased costs all around.
