Array operators return tuple instead

[taonos]

I have a use case where each signal has a different data type. After some transformation is done to each signal, they will be sent out together as network request. Since their types are different I can't put them in one array. As it stands, array operators like merge2All require all signals to be of the same type. Sure I can cast them to AnyObject but that's just way too verbose, and I will have to cast them back in order to send over network.

I think it's better to use tuple instead of array, in which case any types are allowed.

You are right.
Though using array is simple and scalable, it lacks in type safety.
I will add tuple version in future version.
