I didn't realize that worked, but it does. So...
enum offsetOf(alias A) = A.offsetof;
But I have no idea why anybody would want to wrap this trivial
expression like that.
And, I have no idea if the, hmm, /unconventional/ D offsetof semantics
are in the bugzilla. It's not really a "bug", but a design mistake...
