XDC2012: Programming languages for X application development

But then, maybe it implies that the toolkit library itself should be written in a different language (hence pushing the language/{C,C++} frontier inside the toolkit and under the responsability of the {Gnome,Qt} project). Application developpers would lose some choice (but that's the objective after all).
However, in this case, the choice of the implementation language is critical and, given the number of available alternatives and the current domination of {C,C++}, it is pretty easy to predict an enormous resistance to change.
I wonder if someone will be able to challenge the situation someday. IMHO, Amulet (CMU) was the last attempt in the research domain.
Maybe Vala is another one that has its chance (in the Gnome realm)?
QML is interesting too (in Qt realm) but it seems to be more of an evolutionary approch than something disruptive (maybe that's more reasonable btw).
