Do not use a.set_b(value); it works, but it introduces yet another way of using
the QML/C++ interface, furthermore the function might not be called set_b in
some future, which is the reason the function is define in Q_PROPERTY
Use a.b = value, that respects Q_PROPERTY, and is slightly more performant,
most importantly it's like all the other settings so noone starts wondering why
this is special.
