please take the time to read all five sentences of 2.5.5,
especially before assuming Lua does not work properly
and/or other people write nonsense.

The fifth sentence is:
"
If the array has "holes" (that is, nil values between other non-nil values),
then #t CAN BE ANY of the indices that directly precedes a nil value
(that is, it may consider any such nil value as the end of the array).
"

So 3 is perfectly ok.


thank you very much
