As one of the main DOM designers for Servo, I've been reading the RFCs for "virtual struct" proposals with interest. One problem I've had is that I have found it difficult to translate the examples included into meaningful commentary with regards to how this would impact Servo's implementation. Accordingly, I've put together https://gist.github.com/jdm/9900569, which is a minimal example of the C++ features that Servo is currently emulating (or planning to) using unsafe code. I'd appreciate it if we could lean on the example when discussing pros and cons of the various proposals, as well as when demonstrating equivalent Rust code, as that will help me provide better feedback.
Cheers, Josh
