Before continuing with this recipe, it is strongly recommended that you go through the previous one, Creating cooked user-defined literals, as general details about user-defined literals will not be reiterated here.

To exemplify the way raw user-defined literals can be created, we will define binary literals. These binary literals can be of 8-bit, 16-bit, and 32-bit (unsigned) types. These types will be called byte8, byte16, and byte32, and the literals we create will be called _b8, _b16, and _b32.
