You mean if you call D functions in C++, you have to use rt_init 
to enable the garbage collector. I don't see that mentioned on 
the Interfacing to C++ page. Probably worth adding.

Other suggestions:
1) Split up the C++ templates section of that page, instead of 
just being big blocks of code.
2) In the memory allocation section, it mentions for ways to 
ensure D garbage is collected properly by C++. Might provide a 
simple example of each technique.
