Default(T) return type

[TonyValenti]

Hi All,
I noticed that it seems as though a number of attributes have been introduced to deal with the fact that default(T) is not null when T is a struct and default(T) is null when T is not a struct.

It seems to me that with the upcoming changes, it makes sense that default(class) should only be allowed if the class implements a non-null "default" operator. Anyway, just a thought.
