Is this not correct? If I instead dup'd an array of ints (or some 
other non-reference elements) and cast to immutable, would I be 
in danger of undefined behavior?

Try upgrading you compiler to the just released 2.067, it works 
for me with that version.

Actually, it's 2.066, but regardless, dup and idup were turned 
into free functions, so that will probably fix some bugs where 
they didn't work with shared or weren't nothrow or somesuch (or 
if it doesn't, it puts them one step closer to it).
