D doesn't have a preprocessor. This article shows how to do in D what would be a task for the preprocessor in C.
D compilers come with a builtin code coverage analyzer. This article explains why and how to use it.
This article is about exceptions and how RAII and scope guard statements relate to them.
Function hijacking is when old code accidentally calls a newly added or changed function because it shadows the intended one. This article is about how D prevents different kinds of hijacking.

This article is about the D idiom of implementing variadic functions with variadic templates.
Steven Schveighoffer writes about slices and dynamic arrays in D. Unfortunately, this article uses slightly different terminology than the language reference: What the article calls a slice is a dynamic array in the language reference, and what the article calls a dynamic array is not named specifically by the language reference. Still, the article is a great help in getting a good understanding of D's array semantics.
