#X1. Type: float[5] // An array type with 5 elements
#X2. Return value: float[5] func() { ... } // Function with a 5-element array return value
#X3. Array constructor: float[3] (1.0, 2.0, 5.5) // 3-element array with given elements
# // Fails with array of matrices!
#X4. As unnamed parameter: void func(float[5]);
#X5. Variable declaration: float[5] a; // Equivalent to float a[5]; (?)
#X6. Empty brackets: float x[] = float[] (1.0, 2.0, 3.0); // Size of x is 3
# float y[] = float[3] (1.0, 2.0, 3.0); // Size of y is 3 (equivalent)
# float z[] = y; // Size of z is 3
#X7. Testing that 2-dimensional arrays don't work: float a[5][3]; // Illegal
# float[5] a[3]; // Illegal
#X8. Testing that array declaration with dynamic variables as array size won't work.
#X9. Testing length() operator: z.length(); // Returns 3 for z defined before
#X10. Test C/C++ style {}-constructor
#X11. Test struct arrays
#X12. Test array element access at initialization with const/dynamic values
