I'm currently trying to pass a delegate to a shared member function to a 
function. The compiler tells me that the type I'm passing is
(void delegate(const const(char[]) str) shared)

When I try to use this as type for the function argument, it does not 
accept it. I tried various combinations but couldn't find one that does 
work.

So what is the correct syntax for a delegate to a shared member function?

The only way I've found to do this that works is using an alias - this 
is probably worth a bug report if there isn't one already.

class A
{
     // Note that you get forward reference errors if you opt to
     // infer the return type here. That's also a bug.
     void method(const const(char[]) str) shared
     {
     }
}

alias typeof(&A.method) shdg;

void foo(shdg foo)
{
}

void main()
{
     foo(&A.method);
}
