    if ( function ) then function() end seems the way to go then.

    I would suppose that a simple bit flag set during the compile could mark
empty functions which Lua could then ignore.  A very small win which only
really helps code clarity.  It wouldn't be as good as having Lua do some
real inlining during compilation as you suggest.  Ooohh... and const
objects.... one can dream. =)
