#### 15.1.2 Specialized Arrays

An array can be a general array, meaning each element may be any object, or it may be a specialized array, meaning that each element must be of a restricted type.

The phrasing “an array specialized to type <<type>>” is sometimes used to emphasize the element type of an array. This phrasing is tolerated even when the <<type>> is t, even though an array specialized to type t is a general array, not a specialized array.

Figure 15–1 lists some defined names that are applicable to array creation, access, and information operations.
