That's exactly because I didn't want to go into the (usually) tricky
business of changing a table while using an iterator over it. :)

I think what you were demonstrating is that ipairs follows the Lua
convention for arrays, which start at index 1 and goes (quote from
manual) "up to the first integer key absent from the table"... And
"absent" in this case also excludes any "remembered keys", as also
evidenced by your script. This is well-defined and well-documented
