Difficulty using penlight pl.class

[Alfredo Palhares <masterkorp@...>]

Hello lua-l,

I am trying to use lua penlight, it looks awesome. But I am having
problems using the :__Init(), so I did a wip commit to my
awesome-config-files repo[1] please checkout to the
enhancement/multiple-batteries branch, and run the battery.lua simple
script. It looks the the _Init() function of the power_supply its not
being called when I instance the object.
Any ideas?
