This is illogical, because Lua is a versioned language, and each Lua
version is defined by the corresponding open-source implementation and
manual, modulo bugs.

For the record, the description I gave is based entirely on the manual
for Lua 5.4 (but either one could still have bugs).

It may also be correct for other versions of Lua, though.
