So Tango's first beta has been released. So the first thing I did, was to go and ask when and if Derelict will support it. "In the very near future."
I will be using Tango exclusively from now on because as far as I'm concerned it's far better than Phobos. That might be my Java background talking too.
I'll start of by converting the existing lessons to Tango. That shouldn't take too long, as they don't have many dependencies to Phobos. But first I have to wait for Mr. Parker to add the support to Derelict.
