SImple C++ code to D

[Alexandre via Digitalmars-d-learn]

Oh!
I used the RefCounted because this:
"The proposed C++ shared_ptr<>, which implements ref counting, 
suffers from all these faults. I haven't seen a heads up 
benchmark of shared_ptr<> vs mark/sweep, but I wouldn't be 
surprised if shared_ptr<> turned out to be a significant loser in 
terms of both performance and memory consumption.

That said, D may in the future optionally support some form of 
ref counting, as rc is better for managing scarce resources like 
file handles. Furthermore, if ref counting is a must, Phobos has 
the std.typecons.RefCounted type which implements it as a 
library, similar to C++'s shared_ptr<>."

I found that in this link:
