I'd like to define a struct filter_t such that i can define methods get(string key, filter_t filter) and scan(string start_key, string end_key, filter_t filter) and then specialize filter_t as column_filter_t, time_filter_t, etc.
Right now we have a dozen get_ methods, which is bad enough as it is but now we are facing a copy/paste to make scan versions of each. Please tell me there is a better way. -Jonathan
