[FEATURE] len() expression for arrays

The len() expression works for datasets, but not for arrays. It would be great if this expression would accept arrays as parameter in perspective bindings.

You can work around it by using a script transform.

Thanks for the tip. That is exactly what iā€™m doing but i think it would be more elegant if the expression could handle this without a transform.

Keep your eyes on 8.0.4 ā€“ you may find a few goodies for arrays and document tags. :zipper_mouth_face:
