Basically it is now only a storage-container, doing any computation on it by now is not yet possible I think…

1 + na

doesn't even work…

The plan it to get all numerical function working in the next releases… It is for a good reason experimental still…

Hi Sander, thank you for your response! Well - that is my suspicion, too, but it is just a suspicion. As a consequence code containing those function would be apt to break in future versions. This is not unimportant to know - therefore my question. Regards -- Henrik
