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}
16
> =#{nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,nil,1,2,3}
