It is not a violation when the property is a value type, say, an int
that is calculated by the property function. Otherwise, what to return
when the value does not exist as a member?

I think the "get" prefix is overused. Contrary to popular guidelines, if
a function returns a value (property or not), it is acceptable and
usually more useful when the function name is a noun:
cpu.temperature;
is more useful to me as opposed to
cpu.getTemperature();

They are nothing compared to 'sort': :)
