New submission from Alexey Burdin <longsillyusernamealreadytaken8 at gmail.com>:
```
answers_field_order=sorted(
set(j for i in data['items'] for j in i),
key=cmp_to_key(lambda x,y:(
-1 if (x,y) in answer_order
else (0 if x==y else 1)))
)
```
when the cursor is placed in line 5 col 31 (between `)` and `))` ) hitting Ctrl-0 (Show surrounding parens) produces an error sound, though there's no error, the script works fine.
```
