In that case, the problem is that you also have to .dup the aa:

Dfr:

The short template instantiation syntax only supports a single

map!(to!(Variant[string]))(lols);
That is better written:
lols.map!(to!(Variant[string]));
But I don't know if this is

I currently has all stuff wrapped in Variants because it is

Yes, because you are converting this from a const(S) to an S to return
it.
Try:

return this;
}
If I remove const from save(), then it works, but with const there, it
doesn't.
