betterC doesn't change the language, it just doesn't compile in 
all the features automatically. So rules about nothrow etc. 
decorations are still in place, even if the feature isn't 
actually available at this time. The same code you build with 
-betterC can almost always be built without the switch too, and 
continue to work the same way.

That may be a temporary restriction. It is already possible to do 
exceptions with -betterC code if you link in the functions 
yourself (notably, betterC modules are permitted to be used in a 
regular druntime based application), and in the future, such may 
be done automatically on demand too.
