I like it!
It's been a good collaboration...

better solution).
And you were right. I did search

For reference, this is the more correct way:
```d
while (cast(TypeInfo_Array) v.type !is null) {
Variant elem = v[0];

}

Hard to blame anyone for not coming up with that on their first
try, especially since

Thanks for the advice.

As demonstrated by the assert statement, .type returns the typeid
of the underlying type. How would I obtain the actual type such
that:
auto vb = v.base;
