This works:

This doesn't work:
enum MAPSIZE = 3;
ubyte[MAPSIZE][MAPSIZE] map1 = ubyte(1);
void main() {}
Why isn't this working?
I'm afraid I don't know. I would guess it's something to do
with trying to initialise the array in the global scope but
you've also changed the expression in the non-working example.
I don't have access to my machine at present so I can't
experiment!
More generally, it's because one is static (as in global /
thread-local) and the other is not. Take the working example, put
"static" in front of the declaration, and you'll get the same
error.
There are different rules regarding the initialization of static
and non-static variables. My guess, they're implemented as
separate features in the compiler, so when vector operations were
introduced, nobody thought to implement this feature as a way to
initialize static arrays as well.
