This is the real point of my email. There is division along a Qt and non-Qt 
boundary on things like this. 

It is analogous to different sides voting in a referendum: Each side is 
completely perplexed with the other and can't understand their thinking, 
thinks the other side is 'stupid' or otherwise low-quality, and doesn't want 
to waste time understanding it.

For people who learn programming and learn C++ by learning Qt (myself 
included), the Qt implementation seems familiar with all the raw loops if 
you have never encountered the alternative.

However, everyone else is excluded by it. When my colleagues find long 
functions, lots of nested if()s and for()s, ++foo somewhere in while loops, 
they find it much harder to reason about the code. Now I do too. 

So, by sticking to lots of raw loops, you're actually actively excluding 
other parts of the C++ community from participating. I don't have numbers to 
qualify it, but there seems to me to be a much larger community following 
modern C++ practices than following Qt practices on questions like this.

I encourage you and everyone else to dive into it.
