Thanks, that was what I was looking for. Unfortunately, I think I've configured something wrong in git or ssh, and cannot clone the arc repo for actually using it ;)
By temporarily, I originally meant without defining a shadow function, like you did, just reorganizing them for the single call. But that might not be easy to do in a concise, flexible way so I suppose shadow functions make the most sense.
As for the silence, it appears almkglor and stefano are busy working on hl (http://github.com/AmkG/hl/tree/master). I don't know if they still read the forum. I suspect a lot of other people are getting disheartened.
Also, until there's another release of Arc, there isn't much to talk about.
Yes, I think I've followed all of the guides. However, I keep getting the "Permission (publickey)" error. I wonder if there are more configurations like username or email address that have to be the same as what github expects?
