What I’d favor, as an alternative of rvalue references, is momentary copy constructors/project operators.

What I’d favor, as an alternative of rvalue references, is momentary copy constructors/project operators. Similar to with the ‘explicit’ keyword, a key phrase like ‘temporary’ earlier than the constructor would indicate that the given object can be destroyed simply after the constructor call, allow optimization of constructors and project operators, with out interference from the type system. That’s, of course, an almost random thought on a thorny downside; more thought would certainly be required. March 6th, 2012 at 10:09 am For the time being I still think rvalue references are an excellent thing. They're complicated, sure, but I don’t suppose this complexity is well avoidable. At least, I trust that individuals working on the committee wouldn’t have missed a better way if there was one. March 6th, 2012 at 10:35 am “There doesn’t appear to be a way to supply such a move constructor. The more normal conclusion appears to be this: function templates with arguments of rvalue references which can be formed immediately from template arguments can be remodeled, with unpredictable results, foam concrete yeovil to features which have lvalue references as an alternative.
