using setfenv recursively

["Matthew Armstrong" <turkeypotpie@...>]

Is it possible to use setfenv recursively?  When I call setfenv, it attaches to the function, but it seems like it should more naturally attach to the function's call.  

I have a little wrapper function to protect my environment:

function protectedEnv(func)
    local env = {}
    setmetatable(env, { __index = _G })
    setfenv(func, env)
    return func
end

...

myFunc = protectedEnv(
    function()
        -- If I call myFunc inside here, my environments start colliding.
    end)
    
...

myFunc()
