Sigh ... my suggested "minor edit" above produces a "map result" 
instead of
the desired native array ... here is the **fix** by appending 
".array" at the
end (which is the suffix Steve originally offered).  The 
following gives
the desired **bool[]** result.

```d
import std.array;

    auto z5 = jj["ba"].array.map!(v => v.get!bool).array;
    writeln("typeid(z5): ", typeid(z5), ", z5: ", z5);
    writeln("z5: ", z5);
```
