Yes. I put them in a long time ago, before we had the language rule
saying that default arguments were instantiated separately from the

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!
