> I propose adding static method {{LoadableDetachableModel/AbstractReadOnlyModel .of(Supplier<T>)}} so this can be used to quickly create ad-hoc models in Java8 using lambda syntax. (but does not require Java8 in any way). [{{Supplier}} is from Guava library|http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Supplier.html].
> Sample usage:
> {code}
> add(new Label("slug", 
>     LoadableDetachableModel.of( () -> personRepo.slugFor(getModelObject()) )));
> {code}
> Similar approach for other abstract classes can also be useful for implementing typically single methods like {{onSubmit}}, {{onClick}}, {{onConfigure}}, etc.
