      The following generates invalid code:

      pragma Strict
import QtQml

QtObject {
    function absMinusOne(amount: real) : real {
        if (amount < 0)
            amount = -amount;
        return amount - 1;
    }

    property real a: absMinusOne(-5)
    property real b: absMinusOne(10)
}

      Produces -6 for property 'a'. In the "amount - 1" expression it doesn't use the register it stores the new amount in, but rather the original argument.
