POUNCE. Methinks that the indoend thing would aided by a currentenv() function...

here's a hackish version:

function currentenv()
   local getlocal = debug.getlocal
   local e = nil
   local x = 0
   while true do
      x = x + 1
      local n,v = getlocal(2, x)
      if not n then break end
      if n == "(environment)" then
         e = v
   return e
