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

No, I don't think so. Don't confuse 'Element' with 'data'. Element is
a type, it doesn't have a length property. But it does have sizeof (an
example of Element is an 'int', which is 4 bytes long).


Oh, fud. I did get that wrong. I still think it's wrong as I'm not sure anything has 0 sizeof and even then that should be static assert.


You are right.

It happens that the verification Element not null. static assert would be better.
