static const and user attribute

[Jack Applegame]

Which difference between enum and static const with initializer?

struct A {
     @("enum") enum int c1 = 10;
     @("const") static const int c2 = 20;
}

static assert(__traits(getAttributes, A.c1)[0] == "enum");
static assert(__traits(getAttributes, A.c2)[0] == "const"); // 
error
