I've recently come across two pieces of code using calls to callGeneric() inside the definition of a method. In both cases, it appears to me that the callGeneric call could be replaced with a "real" call to the generic, say foo(x) instead of callGeneric(x) inside method foo. My understanding from the docs is that when called with arguments, it is just like calling the actual generic. Clear enough, but what does this provide that just calling the actual generic doesn't? Similarly, when would one want to make the recursive call that results from calling callGeneric with no args? Thanks, + seth
What is callGeneric used for?

In the case of arithmetic methods you might not know or care whether the generic is, say, + or -.
