If I'm not making a mistake, this syntaxe is working starting Lua 5.2 and is not reconize by Lua 5.1 ? (it's make my code compatible with as large as possible Lua version).

In fact, the concept is to have Lua embedded in Séléné (like it is in Conky) which makes easier (for me :) ) internal dependencies management and it's consistent with my other project (Marcel) where Lua is "only" an enduser helper.
Anyway, I keep this in mind for other project more Lua centric.
Nice W.E.
