The array itself is statically allocated in your class, but a string is just a
pointer to a malloc() allocation.
By doing this, an object of your class will take at least 4096 * 16 * 4 = 256

What do you mean by being "malloc'd" in a static section of ram once ???
There are two types of arrays in Gambas:
- "static arrays", declared with DIM array[x, y] AS Type
- "dynamic arrays", declared with DIM array AS NEW Type[x, y]
The dynamic arrays are true Gambas objects, like in Java, but not static ones.
Static arrays are allocated directly in the object they are declared (or in a
temporary allocation if you declared them as local variables in a method).
