Be careful, this may not always be what you want. For example:
```d
enum data = [ 1, 2, 3 ];
void main() {
auto buffer = data; // GC allocation
...
auto tmpBuf = data; // another GC allocation
...
assert(buffer is tmpBuf); // fails
}
```
Whereas:
```d
static immutable data = [ 1, 2, 3 ];
void main() {
auto buffer = data; // no GC allocation
...
auto tmpBuf = data; // no GC allocation
...
assert(buffer is tmpBuf); // true
}
```
