I'm not sure it is very useful. I can think of a couple of reasons to define 
simple getter / setters:

- must be done when implementing an interface
- binary compatibility perhaps (again: interfaces)
- you will or might add functionality to the get/set functions at a later 
stage. 

If these are the only reasons, I would just go ahead and implement the 
get/set functions manually. Then again it may be useful depending on your 
application. 

One more thing you could use this for is adding functionality to get/set 
functions:

template DefaultImplementation(T, string name)
template LoggingImplementation(T, string name)
template UndoRedoImplementation(T, string name)

mixin var!(DefaultImplementation(int, "_name")
mixin var!(LoggingImplementation(int, "_name")
mixin var!(UndoRedoImplementation(int, "_name")
