Indeed, but IIRC it only warns when using multiple strings, like 
.arg("string").arg("other"), not with, for example 
.arg("string").arg(5). Whereas it's still considerably faster (and I 
presume more "efficient") to do .arg("string", QString::fromNumber(5)). 
Even just a single .arg(QString::fromNumber(5)) seems a little faster 
than .arg(5).
