A perfect example of why deprecating __ipairs was the wrong move. It
ought to be possible to make this code work with ipairs(t) as well, but
with no __ipairs metamethod it can't be done.

Except of course by the simple expedient of replacing ipairs(t) with a
version
that does what you want it to do directly! Even, if you insist, with a
version that
uses a metamethod __ipairs! The metamethods on both pairs and ipairs have
always baffled me with their utter triviality!
When writing a library, you cannot assume you can monkey-patch other
people's standard libraries at will.
Not everyone writes Lua code in a situation where they can play God
with the environment.
