Totally overlooked a 'small' problem with RefCounted: It can't work for cairoD ;-) In cairo the c handle is already reference-counted, so I should use cairo_*_[de]reference(ptr) instead of my own counter, but that can't be done with RefCounted. I think I'll have to adapt the RefCounted implementation for cairoD. But I can still use RefCounted in other projects. BTW: RefCounted also uses std.algorithm.swap in it's opAssign. Still wondering what that's supposed to do. -- Johannes Pfau
