initilaize static const array

[tuli]

hi,

this is what i would like to do:

//test.h
class test
{
static const int test::arr[5] = {1,2,3,4,5};
} 

but i am not allowed to...
Instead i have to initialize the array separately

//test.h
class test
{
static const int arr[5];
}

//test.cpp
const int test::arr[5] = {1,2,3,4,5}; 

Out of interest, why?
The first version seem a lot more intuitive to me; and all the code & data is nicely in one place.
Does the actual way yield any advantage i dont see right away?

just wondering...
