There is Nullable in Phobos. This is not really an Option, I 
know. But just in case.

But back to integration tests, there are indeed only few 
possibilities to mock something. However, the basics are there.
I found a section of code generation a while ago in std.typecons.

There are Black and White holes there, for example, which could 
help to implement a basic mocking framework.
