You can cast the function.

Smart.
Unfortunatly, in this case, I'm trying to call "string.dup".
It would appear though that (apparently), dup is a property
that returns a function pointer, or something. In any case, I
can't seem to be able to get its address.
Now I feel kind of bad for suggesting banning taking the
address of a property function ...
I can bypass this with a wrapper function I guess, but at this
point, I'd have to bench to see if that is even worth it...
So, you want to call function (which throws) from function
marked as nothrow? It seems to be breaking idea of what nothrow
does.
You can do this in general by casting (which is preferred way)
and by exploiting current holes/misspecified tricks/corner
language cases which should be in general avoided.
Unfortunately, it appears that you cannot cast in your
particular case of array duplication. However there are other
ways to break nothrow and you can use them (declaration
mismatch, unions, delegates). I think the problem is not
absence of ways of doing what you want, but in limitation of
casting with respect to some properties of built-in types.
By the way, I would not say that dup array property cannot
throw exceptions.
In this particular case, in is an string dup, so it *should* be
nothrow.
Still the final solution has is more problematic than anything,
so I'll just try/catch.
