Is there really any practical difference between these two:

local LocalVar = sqrt(10)

on openstack
    do  thingsthatneedthatvariable
end

and:

local LocalVar

on preOpenStack
    LocalVar = sqrt(10)
end

on openstack
    do  thingsthatneedthatvariable
end

If you could define and set variables like you can in many other 
languages, those lines would have to run on preOpenStack anyway, 
otherwise you can run into issues, where a handler is called before 
the variable is set.
