You can make sure that only specific things are alowed to be thrown, 
using the [throw] keyword as in
	void func ( void ) throw (my_exception, string) { ... }
This would mean that only exceptions that throw my_exception and string 
and unknown exeption can come from here, although while the compiler 
may tell you about [catch]ing an exception that can not be thrown by 
the function, in C style it would not tell you about an exception that 
could be thown not being handled, as you may want the program to crash 
outright. You could easily build / modify a compiler that does this and 
there probably are.

The sun was shining on the sea,
Shining with all his might:
He did his very best to make
The billows smooth and bright --
And this was very odd, because it was
The middle of the night.
