            Bug ID: 218686
           Summary: Web Inspector: ensure that `JSON::ArrayOf<T>` doesn't
                    allow `addItem` to be called with a type other than
                    `T`
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: drousso at apple.com
                CC: inspector-bugzilla-changes at group.apple.com

Right now, `JSON::ArrayOf<T>` always has `addItem` overloads for `int`, `double`, `String`, and `Ref<T>` (even when `T` is not a `JSON::Value`).  This means that I could have a `JSON::ArrayOf<int>` and call `addItem(42.0)` or `addItem("foo"_s)` and it would work.  We should prevent that.
