I use elem(tuples, tuple_size(tuple, -1))
Yes I know there is this workaround, but it is not the intended use of tuples. From the docs:
Tuples are intended as fixed-size containers for multiple elements. To manipulate a collection of elements, use a list instead.
Enumfunctions do not work on tuples.

But then how will I utilize the :u or :j … Thats a bit of a confusing part. It’s necessary for my structure.
If you want advice on this, you must give us some more details about why it is necessary (i.e. how this data is used by your API)
