Is there any way that a nothrow function can call a function

My use case is a pretty low level nothrow function, that needs
to
call something that never ever throws, but was not marked as
such.
I want to avoid the "try/catch/[do nothing|assert]" because I
don't want to pay for that. Ideally, i'd really just want to
mark
my function as nothrow, and have undefined behavior if it
*does*
throw.
Any way to do that?
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...
