ARRAYS

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