[rab] Re-archer: I assume the idea is that it is a double definition. With a dash (hyphen), it can be read as bulls-hitting, which is what archers do. Without, it is what Jeff does. And I've seen "clueless" done that way before, more or less.

[CdM] Thanks - I've got so used to reading 'without' as the opposite of 'within' I forget it can also mean the opposite of 'with'. Also I should have realised this: Cyclops has clued this word in this kind of way before.

I think that clue would be improved by being simply Archer's thing. Like the bust down reason example, it makes the entire clue simultaneously the definition and the cryptic indication.

Well, since BULLS-HITTING isn't a common phrase as far as I'm aware (unlike BULLSHITTING) you'd probably need to write it as Archer's thing? with a question mark.
