A student of ours discovered the following non-compiling code:

class Base { }                                                                  
class A : Base { }                                                              
class B : Base { }                                                              

unittest                                                                        
{                                                                               
  auto c = [ new A, new B ]; // fails to compile but shouldn't A/B be
implicitly 
                             // convertible to Base
}

We think the code should compile. c should be an array of Base. As a work
around you can add explicit casts to Base.
