If you take this example.
@live void addStruct(scope MyStruct* s, const string name, int id)
nameLookup[name] = s;
idLookup[id] = s;
MyStruct* s = new MyStruct;
addStruct(s, "id1", 1);
In the presentation you basically did a copy of the single
ownership in Rust. In the function we assign nameLookup and
idLookup with a borrowed pointer but not as owners. This
currently compiles but your presentation I get the impression
that you are going to put D under full single ownership lockdown.
If I would remove the scope for the s parameter in addStruct then
it would emit an error when trying to assign to idLookup as s is
already consumed by nameLookup.
