Well, as overloading new and delete is deprecated, and the new which is 
part of the language only works together with a GC I don't think that 
anything will be done about this.

Its not a big problem in D because you can't create arrays of objects so 
that multiple constructors will be called at the same time. (Which is 
the biggest issue in c++ with exceptions and constructors). Also doe to 
memory pre initialization the object will always be in a meaningfull 
state, which helps with exception handling too. My replacement just 
calls the constructor, and if a exception is thrown, the destructor is 
called and the memory is freed, then the new statement returns null. 
Works flawlessley so far.
