Make the constructor explicit by adding the explicit keyword.

Right, though they extended the syntax a little further too. You can write:

	int x{0};
	QString y{QString()};

The second one also fixes one of the annoying things in the language: when a 
statement looks like a function declaration, it is a function declaration, 
even if most of the time you wanted to declare a variable. If you replace the 
{} with () in there, it changes to a function declaration.

This also opened up for std::initializer_list, which allows us to now write:

	QStringList z = {"a", "b", "c"};
