I learned about it from the properties chapter in Ali's book:

It's particularly useful for clean interfaces when you're 
wrapping structs allocated by a C library. You may have to do 
various operations behind the scenes, like converting D strings 
to their C counterparts so the data can be used internally, but 
you still want to be able to work with it in the natural way 
`x.names = ["blue", "green", "red"]`.
