Actually I was thinking the same thing, when I wrote it! : ) As I said, it's just a simple usecase. But if you want to push to several arrays in the same loop, it may be handy! Anyway it's not that I'm terribly missing one-parameter push, I just want to understand the underlying idea! And maybe be able to predict in which cases I can use default parameter without looking it up. Cheers Rolf	[reply]
