Closures in const generics cause ICE #63322
Description
Pretty straightforward. The idea is to plug logic into a template. This seems like something that should/could work.
#![feature(const_generics)]
fn test<const F: &'static dyn Fn(u32) -> u32>(i: u32) -> u32 {
F(i)
}
const F: &'static dyn Fn(u32) -> u32 = &|x| x*x;
fn main () {
println!("{}", test::<{F}>(5));
}
