Shouldn't it be possible to use properties
as the type they represent without casting?

I had a property foo of type float which
I tried to return in some other function.

float bar()
{
    return foo;
}

For this to work I must cast foo to float:

return (float)foo;

More problems:

In the subclass to where the property foo is
declared; I'm not allowed to do any of these:

super.foo = value; // foo and value are floats
this.foo = value;
foo = value;

There first returns this error:
'super.foo()' is not an lvalue

The other to this:
'this.foo()' is not an lvalue

(Shouldn't it be 'a lvalue', not 'an lvalue'?)

Can you make a complete source snipped illustrating this? How is foo
defined?

This don't compile with 0.73 until
return foo; is changed to return (float)foo; in the subclass.
The set method works without casting. In my other post
I said that setting like this don't work, but that only seems to
be the case when i qualify foo with this or super.

class bar {
public:
    float foo()
    {
        return bar;
    }
    float foo(float value)
    {
        return bar = value;
    }
private:
    float bar;
}

class subbar : bar {
public:
    float subfoo()
    {
        return foo;
    }
    float subfoo(float value)
    {
        return foo = value;
    }
}
