Yes, yes(?), yes. The following construction in Lua4.0

  function foo (...)
    ... %x ...
  end

is exactly equivalent to the next one in Lua5.0 (as long as _x_ is a new
name):

  local _x_ = x
  function foo (...)
    ... _x_ ...
  end

In my priority list it is very high. But it does not seem to be very
high in publishers' lists ;)
