Just finish some macro project. As for me, there are two limitations now: the first is the enum variant issue (see the syn data structures, ugh); and the second is the lack of reflection (though I think it cannot be a feature in the future also), so I cannot check types in macro

No, I just say that it could be more convenient and safe if I can do type-checking in compile time, instead of pushing it to the runtime

I hope in future versions we get solutions to this limitation. As being said that thanks to
@rustlang team for such a hard work. They consistently shows improvements in rust which is the main reason I'm confident about rust's future. Love this community3 replies 0 retweets 0 likes
FWIW Rust type checking already doesn't happen at runtime. All type checking, including code generated by proc macros, is at compile time.
