Hmmm. I wouldn't have thought that you could get the function pointer at 
compiler time. Regardless, you lose any possibility of inlining the function 
call, which is the main problem AFAIK, though I don't know if they would have 
been an option in the case of dup anyway.

Well, long term, this should be solved by dup actually being nothrow when it 
can't throw.
