The compiler expects member initializers to be known at compile-time. 
Since delegate carries closure, and closure is a run-time phenomena, you 
cannot put it there. That's how I understand it, and I might be wrong. 
Anyway, something like this is possible as a workaround:

struct Foo {
private Exception dg() {
if( m_Dg ) return m_Dg();
return new Exception( "foobar" );
}

private Exception delegate() m_Dg = null;
}
