It doesn't return anything now.

I think returning null is ok. Otherwise a redundant check and a lookup
will be necessary:
Object[char[]] map;
if (auto o = "test" in map) { // this is redundant, in my opinion
delete map.remove("test");
}
and it is exactly the same as:
if (auto o = "test" in map) {
map.remove("test");
delete *o;
}
