Does anybody know an efficient way to get/create-if-missing an lvalue AA

I commonly resort to this, but it uses three lookups.
auto p = key in aa;
if (p is null)
{
aa[key] = inital;
p = key in aa;
}

Depends on your needs, but I find aa.get(key, defaultValue) nice. It doesn't set the value though:
auto p = aa.get(key, initial);
