This is exactly type of code I consider to be bad style and want to see banned. Function that gets rvalue ref should never return it as it knows nothing about its lifetime. Actually, I can't even find scope definition for temporaries in dlang.org, but it is hardly a good thing to rely on anyway. Best is to assume that when function is gone, so is rvalue temporary.
Your code begs for using plain refs and storing Large in a stack variable before calling function chain. May look a bit less convenient but much more reliable and understandable.
