> Alas, the complexity of its meta-object compiler (MOC)

Do these people use the same template when writing about GUIs? I mean what's complicated about MOC? In CMake it's even transparent and the user doesn't even see it. I swear, the same argument is coming back year after year. "MOC" is complicated, but the compiler itself and ld isn't?

This. From 0 to a dialog with a button is quicker in qtdesigner.
