Assigning list<string> to list<var> silently fails

Assigning list<string> to list<var> silently fails, and turns said list<var> into an empty array.

In practice, this rules our using a list<> type for a property that reads from a model which (depending on a platform) may return list of strings or list of integers (typical situation with X11 vs. Wayland identifiers, for example); and I have to resort to this:

property /*list<var>*/ var virtualDesktops: model.VirtualDesktops

Expected behavior

Automatically convert the list<string> value, or list of any other primitive or object type for that matter.

Actual behavior

Silent(!) fail resulting in an empty list instead of a properly populated target.
