Instances of Array store general objects; the arrays size is fixed,
therefore add:/remove: are not allowed.
Access to the individual elements is via an integer index.
Since Arrays are used very often in the system, some methods have been tuned by
reimplementing them as primitive.
Notice that Array is a built-in class (i.e. the VM knows about its
representation). Therefore it is NOT possible to add named instance
variables or change its inheritance. Subclassing is allowed - of course.
Literal arrays (i.e. array-constants) are entered in source as:
#( element1 element2 ... element-n)
where each element must be itself a constant.
Examples:
#(1 2 3)
#('foo' 2 (1 2) 4)
#('foo' #(1 2))
