testException1(x) {
    try {
        doSomething(x);
    }
    catch (e:Error1) {
        println(e);
    }
    catch (e:Error2) {
        println(e);
    }
    catch (e:Int) {
        println("error code = ", e);
    }
}

is roughly equivlalent to:

testException1(x) {
    try {
        doSomething(x);
    }
    catch {
        if (exceptionIs?(Error1)) {
            var e = exceptionAs(Error1);
            println(e);
        }
        else if (exceptionIs?(Error2)) {
            var e = exceptionAs(Error2);
            println(e);
        }
        else if (exceptionIs?(Int)) {
            var e = exceptionAs(Int);
            println("error code = ", e);
        }
        else {
            continueException();
        }
    }
}


exceptionIs?, exceptionAs, and continueException are clay library routines.
