In a similar vein, why does C++ still insist on class static values being set
outside of the class? eg:
struct myclass
{
static int i;
};
int myclass::i = 123;
Why on earth can't I just do:
struct myclass
{
static int i = 123;
};
in the same way that const members are initialised? I've never seen a good
reason why it must be this way and it makes for messy header files.
