Hi,

I think this is a good idea. I've caught myself including both 
<QtAlgorithms> and <algorithm> in a file for the sake of sticking to the 
Qt ones when possible (due to style/convention). This would then be a 
nice mindset change.

It's probably worth to remember that for consistency this might require 
adding more versions of the algorithms already existent in QtAlgorithms. 
I think at least qEqual doesn't have a version which takes a binary 
predicate (as the STL does).


Cheers,
Leandro
