A list? You probably mean an array without holes.

There's no way to do that without traversing the whole table. All
shortcuts that try to infer something from e.g. #t or next() will
fail under some circumstances.

In other words: avoid APIs where you need to auto-detect such a
property. Instead, let the user of the API tell you what they
provide and/or what output representation they want.
