Maybe D is right about GC after all !

As a former C++ programmer, the comment is exactly right, in C++ 
resource management is a solved problem (or at least feels like 
it which doesn't say much), and in D it's way more _complex_ 
(many cases, many workarounds, and _you have to understand it_, 
for example you need a mental model of how the GC works).

There is also a downside to the C++ scoped owership wa: you have 
to find an owner for everything even if they are just memory. So 
small scripts in D will be written almost 2x faster because of 
that and rich stdlib.
