Strong Types for Safe Indexing in Collections – Part 2

by Jonathan Boccara

From the article:

In the previous article on strong types, we set out to find how to use strong types for safe indexing in collections.

More precisely, if we have two vectors with two indices to access them, how can we use strong types to make sure we use the right index for the right vector, and that we don’t swap them by mistake?
