### System information

Ubuntu 22.04.1 LTS

### Issue description

So far I've found these ones:

But there are likely more like them. They are invalid, at least in the context I encountered them here (at the beginning of a regular line of script)

### Steps to reproduce

Type `Anchor` in the code editor.
