If the function collaborates (that is, it has been written to have
a variable environment), my preferred idiom is to pass the environment
as an argument and to get it in a parameter called _ENV in the function.

  function foo (_ENV, a, b, c)
    -- code will run in the environment given as first argument
    ...
  end


Perfect for all my uses :-)
Is _ENV inherited by functions called from foo()?
