"is" operator for structures?

[Gor Gyolchanyan]

Btw, I noticed how classes have two different comparison operators
(one for the reference and one for the object), while they have only
one assignment operator (for the reference only),
I think having two assignment operators would be very good for a
number of cases. Combined with a "final class" declaration it would
essentially be a reference type struct with a default constructor.
I've wanted such a thing for a long time now.
