Subject: Re: [boost] [date_time] default constructor for period?

Yes, you are right! It wasn't std::deque I had the problem with. In fact,
it was std::map; specifically operator[](). Technically, I could work
around that by using insert() and testing the return value and, if
necessary, calling operator[](). But that's neither very elegant nor
maintainable, in my opinion. Especially when I've yet to see a downside of
adding a default constructor.

Furthermore, I have other other container code that depends on default
constructors. Sure, I could workaround period's lack of default
constructor, but wheres the advantage in that?
