>             Project: Commons JEXL
>          Issue Type: New Feature
>    Affects Versions: 3.0
>            Reporter: Dmitri Blinov
>            Assignee: Henri Biestro
>            Priority: Minor

>
> Suppose we have a plain java class which implements a "call" method
> {code}
> public class Foo {
>    public Object call(Object bar) {
>        return null;
>    }
> }
> {code}
> In JEXL we could resolve a function() operator on this class directly, in other words use this class as a closure and invoke a "call" method.
> {code}
> x = new ("Foo"); return x(3);
> {code}
