For scientific visualization, in particular for matplotlib, it would be really good if Python3 had event loop support. In Python2 extension modules such as Tkinter, PyGTK, PyQT each implement their own event loop, leading to incompatibilities. For reliable event handling, Python should be in charge of the event loop, rather than the extension modules. For comparison, see the event loop support provided by Tcl / Tk.
