Is it safe, or do I have to take a snapsot of the keys range

You shouldn't remove anything when iterating over `.keys` or
`.values`. Use `.byKey` and `.byValue` instead to get ranges
that are independent of the aa.
I did a small test using .byKey, it's totally safe, just as you
said. Thank You!
```
void main(){
int[int] aa = [1:10, 2:20, 3:30];
auto k1 = aa.keys; auto k2 = aa.byKey;
aa.remove(2);
writeln(typeof(k1).stringof); foreach(k; k1) writeln(k);
writeln(typeof(k2).stringof); foreach(k; k2) writeln(k);
}
```
