Isn't that tricky to make work with variables that may not even be declared
at the point where one exits the try block?

    try

        if true then
            return
        end

        local x = { }

    finally

        x[ 1 ] = "foo"

    end

"x" isn't even defined at the point where we exit the try block. (I had an
even more twisted version where I used the ability to redeclare local
variables and started the try block with "local x = 3".
