I am using an array of objects, all of which have a common type (They are all sub classes of Field). If I declare an array of these objects, D seems to try to cast them all to the last type in the array, rather than picking a common supertype. This happens even if I specify a type for the array, D still doesn't cast the types properly.

In the error message it also seems that it casts _some_ types properly, but others not, resulting in some very strange error messages. I can work around this by casting all of the elements to the common supertype, but this is not ideal.

Is this a known bug, expected functionality, or should I file a bug request?
