I personally don't consider them strange, but that might be, because I 
implemented them in FPC ^^

Their main purpose should be considered to add functionality to 
classes/records without inheriting from them (which might not always be 
possible, because records can not inherit or you have e.g. the class 
hierarchy of the LCL which you can't trivially change).
