I think it is a little awkward for this function to have the side effect of
returning the contained plugin.

We could instead follow the inheritance approach.  Define WebPluginDocument:

class WebPluginDocument : public WebDocument {
public:
    /* boiler plate */
    WEBKIT_API WebPlugin* plugin();
};

Then, WebDocument would just have the simple method:

    WEBKIT_API bool isPluginDocument() const;

Folks would then use WebPluginDocument like so.

    WebDocument doc = ...;
    if (doc.isPluginDocument()) {
        WebPlugin* plugin = doc.to<WebPluginDocument>.plugin();
        ...
    }

Unfortunately, WebNode (which WebDocument extends) doesn't have a to<T>
method.  It just has a toElement<T> method, which should really just be
renamed to<T> so that it can be used with derived types that are not
elements.  For now, we could just add a copy of toElement<T> named to<T>,
and mark toElement<T> as deprecated.  You can leave it to me to clean up
the deprecated usage.

nit: "use toConst() instead"

nit: "e" stood for WebElement probably in the case you copied this
from.  how about using "d" for document instead?
