Custom JS objects seem to confuse the transpiler

[sotonin]

var self, routine;

self = this;

routine = {
    enemies: false,
    targetNearby: function () {
        routine.enemies = self.findEnemies();
        for (var i = 0; i <= routine.enemies.length; ++i) {
            var enemy = routine.enemies[i];
            if (enemy) {
                var distance = self.distanceTo(enemy);
                if (distance <= 35) {
                    return true;
                } else {
                    return false;
                }
            } else {
                return false;
            }
        }
        return false;
    }
};

while (routine.targetNearby()) {
    self.say(routine.targetNearby());
}

This code seems to confuse it. routine.targetNearby() should return a simple true or false if there is a target nearby that satisfies the distance requirement. It's returning [Object Object] as per the heros say. My best guess is that it's actually returning the function object itself instead of executing the function. but thats just a guess.

With the interpreter, this kind of code now gives a new error:
