Load code from string without using loadstring() function

Question

There is any way to load code from string without using a loadstring() function?

For example:

local code = {
    {
        Code = [[
            function DoSomething()
                print('making something')
            end
        ]]
    },
    {
        Code = [[
            function DoSomethingElse()
                print('making something else')
            end
        ]]
    },
}

for i = 1, #code do
    local currentCode = code[i].Code
    -- Load this code here, without loadstring()
end

App where I'm writing uses a Lua version that doesn't have the loadstring() function. There is a load() function, which works the same way, but it is not a safe way to load code. It can be easily intercepted. I would like to keep my code as secure as possible.
