DMD 2.063

void main()
{
  int delegate() a = ()=>5;
  int delegate() b = ()=>5;
  auto c1 = a+b; // passes (and will crash if c1() called)
  auto c2 = a-b; // passes (and will crash if c2() called)
  auto c3 = a/b; // a & b not of arithmetic type
  auto c4 = a*b; // a & b not of arithmetic type
}

DMD properly rejects all arithmetic if delegates are typed as int function()'s.
