Static arrays as passed as the address of the first element.  So yes, 
that's 'by reference'.


These two are implemented in the exact same way:

void func(int[3] array);
void func(int* ptr_to_some_ints);

// used like:
int[3] array = [1, 2, 3];
func(array);
func(array.ptr);


The important difference is that inside the second function, the 
compiler does not care about how many elements 'array' contains, and you 
don't get automatic array bounds checking.
