[Pharo-users] Conveying the usage of an object

Hi, In other smalltalks, which had the capability of marking a method with more than one category, I could make a method public/private AND it's functional category (accessor, printing, etc) I did this to explicitly show the user which methods I expect to be sent to the object and which ones I don't. It didn't seem to me I can assign more than one category in Pharo, so my question is: How can I deal with this problem? Which is "the Pharo way" to accomplish this?
