Maybe a good idea for a post. But the amount of reaches required makes this icky.

• Pretending people write:

  let Ok(x) = read_input() else { return Err(Error) };
  

  instead of

   let x = read_input().map_err(|_| ...)?;
  

• Pretending people write:

   const x: &str = "...";
  

  instead of

   const X: &str = "...";
  

• Pretending there exist people who have such knowledge of rust macros hygiene, ident namespaces, etc, but somehow don't know about how macro code expands (the "shock" about the compile error).

Maybe there is a reason after all why almost no one (maybe no one, period) was ever in that situation.
