Error passing return value of a generic function to generic callable

[jvasileff]

Somehow the value for the parameter i to op doesn't think it's an Integer:

shared void noMethod() {
    exec {
        op = (Integer i) => i.times(2);
        argFactory = () => [1];
    };
}

void exec<Args>(op, argFactory) 
        given Args satisfies Anything[] {
    Anything(*Args) op;
    Args() argFactory;
    print(op(*argFactory()));
}

produces:

/.../sandbox.ceylon.snapjs.base-0.0.1.js:145
        return $t1j.times(2);
                    ^
TypeError: Object [object Object] has no method 'times'

ok this only happens with named-args call. Looks like something to do with boxing is missing in named-args calls.
