Cool, that is excelent news. Last message about that that I saw was from 2010. Will the integration be as tight as with Vala and GTK/Gobject/Glib?
I think the only way a new language can gain ground is by doing one thing better than all the alternatives. Like Vala does right now, it seems to be the prefered language for GTK/Gnome development right now. Even for some system tools, which is quite amazing.
