Sounds useful to me as well. Would it make sense to have an operator to 
(:if:) that simply returns the number of attachments? I'm assuming this 
would allow you to do:

	(:if attachments > 0:) ... (:ifend:)

Ahem... maybe it'd be better doing it like this:

	(:if (:attachments-count:) > 0:) .. (:ifend:)

or back to the original idea:

	(:if attachments-exist:) ... (:ifend:)

Regardless, I'd prefer having this in the conditional markup.
