Maybe, but this shape is random - it would be different in different
conditions, as the length of the returned array is just some random
memory location.

Since there is no obvious solution, the only rationale for not raising
an exception I could see is to accommodate often-encountered special
cases. I find returning [0] more confusing than returning empty
arrays, though - maybe there is a usecase I don't know about.
