An Ownership/Borrowing system like the one Rust uses? Rust is sadly not (yet) able to use its stricter rules about ownership and aliasing for optimization, because the LLVM backend has been shown to have a number of bugs that prevent such optimizations. Sadly, I'm not that knowledgeable on optimization. Do you expect that such optimizations would make most programs significantly faster or is it more of a special case that would not improve the performance of most programs? Keep up the good work with D. I especially love its template/metaprogramming capabilities!
