Matching classes causes a stack underflow, no clue why. That's for a different pr though. |

You could also use let-else, to prevent rightward drift.
let Some(name) = n else {
// If no name is provided, simply pop the top of the stack.
emit!(self, Instruction::Pop);
return Ok(());

I know this isn't the code you changed, but if you're looking to make it more rusty, you could use .enumerate() here for the outer loop (for (i, attr) in attrs.iter().enumerate()) and then just for ident in &attrs[i + 1..] for the inner loop.
