This looks like a step back in terms of error reporting. It can be a register name or identifier now as I understand it. However saying "identifier" makes the majority of `register read <oh no a typo>` less intuitive.

Also "undeclared", how would you even "declare it"? That part isn't much help to the user.

Can we produce something like this?
```
Invalid register name or identifier <bla>
```
