So, Lua tables? ;)

Unfortunately, Lua violates Commandment Zero:

Thou shalt not index from one.

:)

That may be fixable at compile time, I believe. In the worst case, you could write a patch. (Dijkstra would prefer a half-open indexing scheme anyway.)

And be incompatible with the universe of Lua programs.

The problem was that Lua reified 1-indexing into the language when they optimized to make arrays faster and then created length operators. At that point, 1-indexing got baked into the language.
