[Interest] QCoreApplication, argc parameter type

[Bernhard Lindner]

Hi!

Can someone tell me why QCoreApplication uses an 'int &argc' type parameter instead of a
plain 'int argc'? Does QCoreApplication expect the value to change? Does it change the
value by itself?

When deriving from QCoreApplication this can cause funny crashes if one forgets to use a
reference type in the derived class' constructor parameter. So I guess there must be a
very good reason why QCoreApplication uses a reference instead of copy-by-value.
