FWIW, I like Georg Lehner proposal as well :)

That said, one could easily "virtualize/overload" the existing io module to suit its need.

For example:

local io = require( 'io' )
local ioopen = io.open

io.open = function( filename, mode, ... )
  -- do stuff depending on mode

  -- or default back to the standard implementation
  return ioopen( filename, mode )
end
