  Sure, if you'll forgive me again for copying over text from a previous post. For context, I'm the author of gecs, which is a compile-time library for generating Entity Component System worlds and performing queries against them during compilation. Over the course of writing this library I encountered a number of limitations of Rust's compile-time capabilities with generics and both declarative and proc macros. Some of them I managed to push through with hacks, but others are simply impossible to solve (at least, as far as I can tell after expending a lot of effort trying) on stable.

  I disagree with this. They're a code generation tool, but not particularly powerful compared to the features I mentioned in C++. They have no understanding of types, can't evaluate constants, can't enforce constraints, can't (easily) determine build configuration in their host crate (via #[cfg]), and so on. There's also no concept of stateful proc macros or proc macro dependencies that pass information to one another. I've been working on a compile-time ECS library (source code here) and it has been a struggle in quite a number of ways.
