--- Comment #4 from Andrei Alexandrescu <[email protected]> 2009-11-22 17:32:49 PST --- (In reply to comment #3) > I guess, why? Why does ++x need to be an lvalue? 1. It's a departure from C. If we do make that departure, we need a good reason, which I don't know of. (Before you reply with that, I do remember you mentioned that dmc yields an rvalue and no client every filed a bug.) 2. For most user-defined types returning a value is considerably more expensive than returning a reference and nontrivial to remove for the compiler when unused (requires context sensitivity). If built-ins return an rvalue and user-defined return a reference, generic code will be gratuitously incompatible across such types. For me reason #2 is the more important. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
