ARRAYS

There is support for arrays. The arrays can't be declared, but should
be allocated dynamically with the function 'allocate()' (see allocate).

Arrays are stored by reference, so all assignments of whole arrays will
just copy the address. The array will be deallocated when no variable
points to it any longer.

When a variable points to an array, items can be accessed with indexing:
'arr[3]' as an example. The name of the array being indexed can be any
expression, even a function call: 'func()[2]'. It can also be another array,
if this array has pointers to arrays:

arr = allocate(2);
arr[0] = allocate(3);
arr[1] = allocate(3);

Now 'arr[1][2]' is a valid value.

The 'sizeof()' function (in true C, not a function) will give the number
of elements in an array (see sizeof).

ARRAY CONSTRUCTOR

Arrays can be constructed with a list inside '({' and '})'. Example:
({ 1, "xx", 2 })
will be construct a new array with size 3, initialized with 1, "xx" and 2
respectively.
