No, D is not capable of doing it already. Without 100% reliable 
destructors, RAII is simply not implementable.

D's destructors are not guaranteed to run on 100% of fully 
initialized structs, which means that a RAII container has no 
way to make sure its resource is actually freed. It is up to 
the implementer. This eradicates almost all of the utility RAII 
was meant to provide.

The only time it may not run, it is when these are collected by 
the GC. Which is not a problem if you want to use RAII, as in 
C++, to not use a GC.

What need to sink in is that, when it come to RAII, you have all 
the same tool as in C++ and can do all the same shit (modulo 
internal pointers), as unasfely as in C++.
