New public API [was: Re: Need to talk off-the-record]

One thing I was thinking about (and even started using in some cases)
is to change methods returing collections. The way it is now:
virtual std::vector<std::string>  getAttributeNames()
This means that whole vector, as well as every string inside will be copied
(possibly twice - inside function when creating retval, and then to the
actual
return value). Now, instead we could change signiture as follows:
virtual void getAttributeNames(std::vector<std::string> &out)
This will avoid unnessesary copying.

Java does not have to worry about it, since it returns references, and thus
only one copy of object is created.
