I have global static array and I want it to initialize in module
constructor, but I get error. I there way to do it without using enum.
immutable int[5][5] arr;
static this () {
arr = new int[5][5]; // Error: slice arr[] is not mutable
}

So you want to initialise it with data acquired at runtime, but make it
immutable once initialised?

I like the simple workaround
with using mutable pointer, but I'm getting access violation error even
when arr is mutable ... and really don't understand why... :(

static this () {
int[256][256]* pArr = arr;

I need to use this workaround because global array I want to initialize

A pointer to a immutable array is immutable. So you aren't improving the code,
just making it more obfuscated. So there is zero need to use a pointer.
Immutable data is
Some people have recently discussed about this problem and a bug report was
proposed. Until some language-supported solution is found, the simpler
solution for this problem may be to use a static mutable array...
