This would be why I like Berophile's suggestion on the main list of having a 
page which lists deprecated and intended to be deprecated constructs. opCall is 
a good solution and basically fulfills the requirements of a default constructor, 
but if it's going away, then it's in the same camp as using scope on a class.
