[Corion]: Hi Lady_Aleena!
[Lady_Aleena]: Corion, how are things?
[Corion]: Lady_Aleena: Quite good ;) I'm working four days now, instead of five, which helps my mood and my weekends tremendously
[Corion]: My Perl output hasn't recovered, but as $work is still somewhat stressful, I don't think this would be different with a five day workdweek
[Lady_Aleena]: Corion, that is a good thing (TM) 8)
[Corion]: And this evening, I'm actually dusting off some old module of mine and bringing it up to the last version of the library I'm wrapping
[Lady_Aleena]: Updating things can be fun, if there is a better way to do it.
[Corion]: Lady_Aleena: Mostly, it's just housekeeping, but it inspires me about things I could do with it, so that's good ;)
[Lady_Aleena]: By the way, I stopped by to let someone know I'm still alive, though I haven't found anything to write in perl for a while now.
