QStringBuilder

Did you know that almost for free you can speed up your Qt applications, by adding a single define to enable QStringBuilder?

What's the catch you may ask - the answer is your code may fail to compile in a few places, and what's worse, it might crash in a few places. The good news, however, is that the crashes will be warned about by clazy, and of course the compile errors by your compiler :-)
