Can't create nested classes

[Bradley Smith]

The crash in the example code isn't from nested classes. It is from the 
destructor of class Writer. The destructor is calling a method on the 
garbage collected member object "testFile". This reference is no longer 
valid.

 From http://www.digitalmars.com/d/class.html#destructors

"When the garbage collector calls a destructor for an object of a class 
that has members that are references to garbage collected objects, those 
references are no longer valid."


In addition, the call is unnecessary because the class File will call 
close() in its destructor.
