I'm writing a blog post about why we don't need rvalue references in
D. It seems that we rely on NRVO being performed, not just as an
optimization, but for correct semantics (e.g. for objects without
destructors or postblits). This doesn't appear to be documented anywhere.
Is it meant to be part of the spec?
NRVO isn't required for correct semantics, as structs can be moved with
bitcopy.
It is required for structs that disable postblit. -- Andrei
