I recently started using C# professionally which has this feature 
already. It makes function with out parameters so much more 
pleasant to use.

Many argue that we should not overload D with even more features, 
but I'd say, if it makes D more fun to use and it is just syntax 
sugar / a simple lowering than we should consider it.
