That is not Lua 5.1, that is Lua 5.0. To get it under 5.1, you need to
have compiled with the compatibiliy option,[1] which is the default,
so that's why people think table.getn is 5.1.
Anyway, it is the easiest possible thing to supply.
table.getn = function(t) return #t end
[1] "Function table.setn was deprecated. Function table.getn
corresponds to the new length operator (#); use the operator instead
of the function." From the "Changes in the Libraries" section
of the
Lua 5.1 manual.
