I use an alternative construction that does the same thing in the end:

local f = function() ... end
return {
  version = "1.0.2",
  f = f,
}

I also think modules shouldn't modify the global namespace.
This solution doesn't allow concatenation of module files but this is
a small price to pay for a simple, understandable module mechanism.
