You don't have to remove the brackets. You just have to process the 
result correctly. It's not an object but an array with an object as its 
first element.

If you're only interested in the first module (e.g. because you know 
that there is exactly one), you can use `j[0]["kind"]`, `j[0]["name"]`, 
`j[0]["file"]`.

If you want to handle multiple modules, you can loop over the array:
----
foreach (size_t i, item; j)
     /* It's a bit silly that `foreach (item; j)` doesn't work. */
{
     /* ... use `item["kind"]` etc. here ... */
}
