currently ZK has @ref to shorten binding expressions

it would enhance the VM programming if a similar concept was available at VM level

in addition to providing a getter/setter to a VM property

public String getTitle();
public void setTitle(String title);

it would be useful to have an additional level of indirection

public Reference<String> getTitle() {}


interface Reference<T> {
   T getValue();
   void setValue(T value);
}

for @bind(vm.title)
instead of using setTitle/getTitle the binding should resolve to

vm.title.getValue()
vm.title.setValue(title)

when encountering a Reference<?> implementation in an EL

this allows to implement reusable and more sophisticated re/loading, saving, caching/lazy loading strategies when accessing viewModel properties without making the UI more complex
