As a somewhat-related data point, Servo is already using the macro deriving infrastructure of Rust to generate these lists at compile time for its garbage collector.

I understand the urge to evangelise, but does Rust have to crop up in every C++ thread?

It was in response to a comment that was referring to Firefox. Servo is touted as the eventual replacement of Firefox's rendering engine. It's literally a response to a comment about Mozilla's current practices in this area explaining their proposed future practices.

Seems appropriate to me.

Apologies if I made it seem like evangelism; just wanted to clarify the state of tracing cycle collection in Firefox-related projects.
