make a nothrow call a throwing function

[monarch_dodra]

Is there any way that a nothrow function can call a function that 
throws, but without even trying to catch if an exception is 
thrown?

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?
