Weird template error

[Brian]

I don't understand why we wouldn't want properties either.  Another issue 
I've had a couple times, although there might be a good reason for this 
I'm not aware of:

class Foo {
	int x;
}

void set(inout int x) {
	x = 10;
}

void main() {
	auto foo = new Foo();
	set(foo.x); // This works fine
}

But then if you need to make x a property:

class Foo {
	int _x;
	
	int x() { return _x; }
	int x(int val) { return _x = val; }
}

You get "Error: foo.x() is not an lvalue"
