Objective-C enables ARC by default for all pointers to Objective-C objects. Since virtually all Objective-C APIs deal with Objective-C objects (or integral values), if you limit yourself to Objective-C APIs you're pretty much memory-safe.
"pretty much" isn't really what we're trying to achieve with @safe.
The point being, D could have managed and unmanaged pointers (like Objective-C with ARC has), make managed pointers the default, and let people escape pointer management if they want to inside @system/@trusted functions.
Yeah, it could, and the design of D has tried really hard to avoid such. "Managed C++" was a colossal failure.
I've dealt with systems with multiple pointer types before (16 bit X86) and I was really, really happy to leave that **** behind.
