Description
PR #279 introduces constant-intialization. Literals or some basic expressions can be evaluated at compile time.
Constant arrays and structs are not properly supported:
VAR_GLOBAL CONSTANT
x : INT := 3;
x_arr : ARRAY[0..1] OF INT = [9,8];
x_strct : MyStruct = (x := 5; y := 7);
END_VAR
VAR_GLOBAL CONSTANT
a : INT := x;
b: INT := x_arr[1]; // does not work
c: INT := x_strct.y; // does not work
END_VAR

Research direction
Start by reviewing PR #279, which introduced constant initialization, then reproduce the array and struct examples in this issue. Trace how constant arrays and structs are evaluated and accessed; done means the indexed array value and struct field value initialize correctly at compile time.
