What do you think about **collapsible if** clippy rule?
rust-lang.github.io/rust-clippy/...
I doubt that I like it, at least in this particular case of nutype.

Interesting discovery, this Rust code compiles, apparently for `const` evaluation the moving semantic has different rules.
Meter does not implement Copy.

For some reason I was ignorant of the existence of std::any::Any and downcast/downcast_ref in #rustlang, but they can be extremely powerful in certain situations!
![use std::any::Any;
fn main() {
let items: Vec<Box<dyn Any>> = vec![
Box::new(5i32),
Box::new("hello"),
Box::new(3.0f32),
];
for item in items {
if let Some(i) = item.downcast_ref::<i32>() {
println!("i32: {}", i);
} else if let Some(f) = item.downcast_ref::<f32>() {
println!("f32: {}", f);
} else if let Some(s) = item.downcast_ref::<&str>() {
println!("str: {}", s);
} else {
println!("Unknown type");
}
}
