I'm guessing as I don't use 2.0 but I think that this is a bug. DMD is trying 
to say that the above returns are trying to return something that can't be 
referenced (like a math expression result).

OTOH that assert is wrong. Element.sizeof will always return 8, the size 
of an array reference. What you want is Element.length.
