Paul King commented on GROOVY-1724:
-----------------------------------

You could try this trick:
{code}
abstract class AbstractStuff {
    String reverse(String value) {
        new StringBuilder(value).reverse().toString()
    }
    abstract String concat(String one, String two)
}

Closure delegateToReverse
AbstractStuff stuff = { String one, String two -> delegateToReverse(one + two) }
delegateToReverse = { stuff.reverse(it) }
assert stuff.concat('1','2') == '21'
{code}

> Currently, it is possible to define Map coercion to interfaces:
> [foo: {}, bar: {}] as SomeInterface
> The mechanism leverages Java proxies and invocation handlers.
> The mechanism should be enhanced to allow extending classes as well.
