I disagree, on the grounds that the frame is a prefix of the shape; therefore a list; therefore its shape is always a 1-atom list. The frame can be empty, with shape (,0), but the shape of the frame cannot be empty.

I think you meant your first sentence to be "It sounds like your

the verb operates on a single cell)."

Empty shape is very different from empty of values.

But our tendencies towards verbal shorthands can mishandle this
"scalar" or "atomic" issue.

Thanks,
