Many examples for Gtk use C code, and I end up looking for the correct GtkD class that offers the function. Otherwise I quite like the classical inheritance that is possible with GtkD, whereas you use the "alias this" trick, which is fair enough. Also you can bind events like onExpose naturally to class methods in GtkD. There is no data pointer involved.

I just noticed cairo.d is still a dummy. I am using image surfaces. "-ffunction-sections -fdata-sections -Wl,--gc-sections" is a good idea, but I found it to break exception throwing for my programs.
