Thank you for the test case. You are correct: all my earlier tests
were false positives "confirming" incorrect assumptions. The result is
dependent on how the table is constructed (as was pointed earlier).

One of the incorrect assumptions I had was that ipairs(t) would
produce the same keys as 1..#t, but it's clearly not the case as 1..#t
may iterate over holes, but ipairs never does this (at least in Lua
5.1).

Paul.
