Nulling a reference to a class with opAssign ...

[Steven Schveighoffer]

Your exact code compiles for me (dmd 1.0.23)...  You sure you are using the 
latest dmd?

One observation, your destructor in Foo should not be accessing barRef 
because the garbage collector cannot guarantee that the barRef instance 
hasn't been collected.  If you are in the destructor, there is no reason to 
clean up GC references anyways, as the GC will handle that.

Erm ... this totally catched me off guard ...

class Foo()
{
     Bar barRef;
     ~this() { barRef.noMoreFoo(); }
     void opAssign(float f);
}

class Bar()
{
     Foo fooRef;
     void setFoo(Foo foo) { fooRef = foo; }
     void noMoreFoo()     { fooRef = null; } // error: can't cast void* to
float ...
}

?
