Subject: [ruby-talk:17286] Re: Inheritance

What I want to do could be expressed in pseudo-C++. 
Assume Exception and ZeroDivisionError be prdefined classes ( as it is
in Ruby )

	class MyException: Exception { }

	class IntDivisionByZero: MyException, ZeroDivisionError {}

	void fn( a )
	{ 
	   if( a > 0 )
	      throw IntDivisionByZero();
	   else
	      throw ZeroDivisionError();
	}

	cin >> v;
	
	try
	{
	   fn( v );
	}
	catch( ZeroDivisionError err )
	{
	   cout << "catched\n";
	}

I'd like "catched" be printed regardles of v's sign. This works in C++,
because it implements multiple inheritance. But Ruby does not. Is there
a way do achieve the same results.
