What's the best way to augment the function named count (.et.al.) to provide the same functionality as db-count ? It seems like I should be able to use multimethods, but don't see how that would work.
The functions themselves could be implemented as multimethods. But that would have a performance impact. However at the moment we have some hardcoded types in the Java implementations of the functions. Maybe the Java implementations in RT could fallback to some -method version? Then you just implement seq-method to get seq for your datastructure. The known things (vector, map, whatever), would still have the same speed. This was already done for print. Sincerely Meikel
