Yes. I put them in a long time ago, before we had the language rule saying that default arguments were instantiated separately from the function. (i.e. if you supply both arguments then the default isn't instantiated) At the time this was the only way to make sure that you could have containers of elements that didn't have default constructors. It was important at the time, but it's now irrelevant.

Thanks again: these days, besides helping improving the lib ;) I'm learning a lot!
