In the pre-Java-1.5 days, functions that took Objects were *very* common; e.g. every collections class. Even now there are probably lingering cases where either there's some code that hasn't been genericized or is too much work to genericize to make it worthwhile. (I do very little Java programming so can't point to any concrete cases if you would (reasonably) reject the example of java.util.collections being used in their non-generic form.) Anyway, the point wasn't that 'foo(Object o)' is common, just that you've probably seen something which is somewhat comparable. Evan
