How to define the "outer scope" ? (-1)
The block you put the do-end in is the outer scope. (Yes, you would have to use a do-end to be able to use export.) 

-- outer scope
do
-- inner scope
export local v = 3
end

or

do
-- outer scope
do
-- inner scope
export local v = 3
end
-- outer scope again
end

            Can we get expressionblocks?

        AKA functions:

        local v = (local function() return 3 end)()



    Basically, but without the GC overhead of creating closures, or
    the VM overhead of calling functions.

    Alternatively:

    do
    <block>
    export local <namelist> = <explist>
    end

    Where `export` would create the locals on the outer scope. This is
    useful when creating closures without polluting the environment.
