Neat flat (8)

I believe the answer is:

straight

This clue is a double definition.

'neat' is the first definition.
(synonyms)

'flat' is the second definition.
(synonyms)

(Other definitions for straight that I've seen before include "Liking the opposite sex" , "Honest, not crooked" , "Unswerving" , "Linear" , "Uncurved" .)

I've seen this clue in The Guardian and the Sydney Morning Herald.
