Hi,

I am trying to do this (vibe-d.0.7.28) 

interface API {
  //Sub-APIs
  @property WebViewAPI webView();

}

class APIImpl : API {
private:
  WebViewAPI mWebViewAPI;

public:
  this() {
    mWebViewAPI = new WebViewAPIImpl();
  }
  //Sub-APIs
  @property WebViewAPI webView() {
    return mWebViewAPI;
  }
}

interface WebViewAPI {
  //@property WebViewMapAPI map();
}

class WebViewAPIImpl : WebViewAPI {
}

but get the following error: 

../../.dub/packages/vibe-d-0.7.28/vibe-d/source/vibe/web/internal/rest/jsclient.d(35,52): Error: no property 'name' for type 'SubInterface'
../../.dub/packages/vibe-d-0.7.28/vibe-d/source/vibe/web/rest.d(293,28): Error: template instance vibe.web.internal.rest.jsclient.generateInterface!(API, Appender!string) error instantiating
../../.dub/packages/vibe-d-0.7.28/vibe-d/source/vibe/web/rest.d(221,24):        instantiated from here: generateRestJSClient!(API, Appender!string)
source/web/webserver.d(82,52):        instantiated from here: serveRestJSClient!(API)

it seems like the SubInterface struct in vibe/web/internal/rest/common.d does not have the 'name' property that is asked for in vibe/web/internal/rest/jsclient.d:

common.d 

struct SubInterface {
	RestInterfaceSettings settings;
}

jsclient.d 

foreach (i, SI; intf.SubInterfaceTypes) {
		output.generateInterface!SI(intf.subInterfaces[i].name, intf.subInterfaces[i].settings);
	}

I expect this is a bug? Or am I missing something? I assume the vibe examples in the 'examples' folder are run also as part of the regression run, and they use sub-interfaces..?
