Assuming f is a function, just do local env = {} env['args'] = {...} setfenv(f, env) return f()

  That is kinda cool, but it does look like a lot of work to bind multiple functions safely into the same environment in any kind of runtime way. Absolutely doable though.

    That's not difficult at all. You can just say env['f'] = myfunc and the function will be available as f within the environment.

      Can be a little verbose as this example shows[1], but works really well in practice. [1] http://stackoverflow.com/a/6982080 http://stackoverflow.com/a/6982080

        That does look really interesting, I'll keep it in mind for the future!
