Reading through that discussion, I wonder why the choice made has been 
to depricate QtAlgorithms, while in that thread it was suggested to 
depricate QT_NO_STL itself. Personally, I'm sad to see them go, but I 
understand the reasoning. I do think that the versions taking a 
container will be really missed though, and I'll probably end up 
creating my own algorithms.h to make that work again.
