digitalmars.D.learn - confusion between conversion between member function delegate and property call

reply Simon Hudon <Simon.hudon gmail_removethat.com> writes:
I have the following code:

class MyClass {
public:
    void memberFunction ()
    {   v = 3;
    }
private:
    int v;
}

void main() {
    auto c = new MyClass;
    void delegate () a = c.memberFunction; // Produces an error voids have no
value
}

What I think is appening is that DMD interprets c.memberFunction as a property
call expression that it can then put into a delegate as a lazy evaluated
expression.  Instead, what I would like it to do is that a points to a call of
memberFunction on the object referenced by c.

Please tell me if you know an elegant way to do it.

Thanks

void delegate () a = &c.memberFunction;
