Would you mean a table just with keys like that, e..g {[0] = 1, [-1] =
2}? Because there #t was always zero. It seems that if the table has
an 'array part' (the [1..n] sequence) then #t gives the length of that
array part. Certainly a lot of code does assume that one can add
things to an 'array' in this way without upsetting the length
operator.
