You are incorrectly assuming the behavior of 5.1 is something other
than it is. Please be aware that the documented problems of using #
on arrays with nils are not theoretical. The undefined behavior using
# on arrays with nils exists today.
For instance, I get the following in Lua 5.1:
> =#{nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,1,2,3}

> =#{nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,1,2,3}
