Feeling a bit brain dead at the moment. I am trying to do a sanity check on user-input before the data gets put in a dao-class. That requires simply checking the col-type for the slot, comparing it to the type for the data and, if they do not match, rejecting the data. 

I can do it looping through postmodern:dao-column-slots using postmodern::column-type, but is there a way of doing it with exported functions?
