That's definitely true, but that leaves the question whether 
lowering rvalue references to lambdas is acceptable. There's the 
'dmd for fast builds, gdc/ldc for fast code' motto, but if your 
debug builds of your game make it run at 15 fps it becomes 
unusable. I don't want the gap between dmd and compilers with 
modern back-ends to widen.
