A prototype for the O/B system:

This is really fascinating, are there some benefits you foresee of this addition to D? I know the O/B system has been popularized by Rust, but have not really thought about it outside of Rust, is this an efforts towards -betterC or will it be used towards those efforts?

An O/B system is a way to:

1. eliminate double frees 2. eliminate use-after-free 3. eliminate memory leaks 4. using undefined pointers

when using explicit memory management like malloc/free. Any D application, including DasBetterC, that uses explicit memory management can benefit from it.
