Hence, you will be less likely to want to enable such debug statements in release builds both due to fears concerning unnecessary increases in binary size, and unnecessary increases in compile times.

Well, if all << operators are inline, it will be optimized. You also don't have to add endl, because "thingy" can add '\n' and flush buffer at the end by default (like qDebug does)
