Use of Ranges in D
Let’s look at the use of ranges in D in this chapter.
We'll cover the following
Ranges are an integral part of D
D’s slices happen to be implementations of the most powerful range RandomAccessRange, and there are many range features in Phobos. It is essential to understand how ranges are used in Phobos.
