* pointer-valued expression whose base type is size N, evaluate its value
|

|
* to A, and yield array elements of the pointer base type at locations
|
||||||
|
* <code>A + N*J</code>, <code>A + N*(J+1)</code>, ...,
|
||||||
|
* <code>A + N*(J+K-1)</code>. But the address of the expression is <b>not</b> modified
|

|
* when an array cast is applied.
|
