Consider:


void foo (int function (int, int) a){}
void bar (int delegate (int, int) a){}

void main ()
{
    foo((a, b) { return a +b;});
    bar((a, b) { return a +b;});
}

Neither call works. The literal does not convert to the function or the
delegate type.

Additionally (this might have been reported), a function type should convert
automatically to a delegate type with the same arguments and return type.
Walter has expressed doubts about that. The doubts are unfounded.
