Considering how much work it is to create and maintain a wrapper for sfml, would SWIG be an alternative to contemplate?
This would open it to more programming languages and bring stuff like cross-language polymorphism for free.

I think it has already been discussed, probably a long time ago.

Basically, I don't want to use such an abstraction because it doesn't take advantage of each language's specific features. I prefer to have bindings that are fine-tuned and 100% compliant with the target language, that perfect clones of the C++ API in every language.

Experience on current bindings showed that many things need to be redesigned and customized according to the target language.

You mean like special property setters and getters like in D and C#?
I thought the generators would do that automatically, gotta test it sometime.

Another issue that comes to my mind is addon libraries. E.g. SFGUI looks very promising, but doesn't have a wrapper.

Yes, and much more. Another example: transforming all the LoadFromXxx functions to constructors (or Create functions in the C binding). I doubt this can be done automatically.

And what about bindings that must use the C binding, not the C++ API?

External libraries can use whatever they like to create their bindings.

If these functions are supposed to be constructors in other languages, why aren't they constructors in C++?

SWIG supports D, so it has to (and I'm pretty sure it does) generate a C layer in between.

Yep, of course, I just wonder if it works flawlessly.
