Groovy TryCatch class

gistfile1.groovy

    public static def _try(attempt) {
        return new TryCatch(attempt: attempt)
    }

    public static class TryCatch {

        def attempt

        public def _catch(clos) {
            try {
                return attempt();
            } catch (Exception e) {
                return clos(e);
            }
        }

        public def getCatch() {
            return _catch { null }
        }
    }

/* USAGE */

def caption = _try { very.long.gpath.find {it.name == "expression"}?.with?.array.operation[0] }._catch { "" }

// null default
[
    width: _try { attrs.width as int }.catch,
    height: _try { attrs.height as int }.catch,
]

Also now that you have a try..catch, what about try..catch..finally?

Did cross my mind. Working on it... ;)
